Java Clean Code Tutorial #2 - Static Analysis FindBugs Eclipse Plugin Setup
Episode 2 of the free Java Clean Code Training Series. In this tutorial I show you how to download and install the static analysis tool FindBugs and run it against your Java Programs in Eclipse or Spring Tool Suite. Findbugs looks for and identifies bugs in Java Programs. It is based on the concept of bug patterns. A bug pattern is a code idiom that is often an error. Findbugs will search for over 200 bug patterns in your code. Bug patterns arise for a variety of reasons: - Difficult language features - Misunderstood API methods - Misunderstood invariants when code is modified during maintenance - Garden variety mistakes: typos, use of the wrong boolean operator, dead code etc FindBugs uses static analysis to inspect Java bytecode for occurrences of bug patterns. Static analysis means that FindBugs can find bugs by simply inspecting a program's code: executing the program is not necessary. This makes FindBugs very easy to use: in general, you should be able to use it to look for bugs in your code within a few minutes of downloading it. Running findbugs will certainly help you write cleaner code by helping to identify bugs, typos, dead code or simple generic coding mistakes. I treat static analysis tools as first class citizens and always execute on my code, regardless if its fun home code or serious production code. Why clean code? Simple. Clean code allows us to confidently make changes and deliver more features quickly to our customers. Don’t forget to subscribe for your regular dose of Java Tutorials! STOP THE ROT.

Combining R with Java for Data Analysis
Java is a general-purpose language and is not particularly well suited for performing statistical analysis. Special languages and software environments have been created by and for statisticians to use. Statisticians think about programming and data analysis much different from Java programmers. These languages and tools make it easy to perform very sophisticated analyses on large data sets easily. Tools, such as R and SAS, contain a large toolbox of statistical tools that are well tested, documented and validated. For data analysis you want to use these tools. In this session we will provide an overview of how to leverage the power of R from Java. R is the leading open source statistical package/language/environment. The first part of the presentation will provide an overview of R focusing on the differences between R and Java at the language level. We’ll also look at some of the basic and more advanced tests to illustrate the power of R. The second half of the presentation will cover how to integrate R and Java using rJava. We’ll look at leverage R from the new Java EE Batching (JSR 352) to provide robust statistical analysis for enterprise applications.

OWASP AppSecUSA 2012: Static Analysis of Java Class Files for Quickly and Accurately Detecting
Speakers: Arshan Dabirsiaghi. Aspect Security | Matthew Paisner, Aspect Security | Alex Emsellem, Intern Software Engineer, Aspect Security Attacks such as Cross-Site Scripting, HTTP header injection, and SQL injection take advantage of weaknesses in the way some web applications handle incoming character strings. One technique for defending against injection vulnerabilities is to sanitize untrusted strings using encoding methods. These methods convert the reserved characters in a string to an inert representation which prevents unwanted side effects. However, encoding methods which are insufficiently thorough or improperly integrated into applications can pose a significant security risk. This paper will outline an algorithm for identifying encoding methods through automated analysis of Java bytecode. The approach combines an efficient heuristic search with selective rebuilding and execution of likely candidates. This combination provides a scalable and accurate technique for identifying and profiling code that could constitute a serious weakness in an application.

ECE2012 - Develop Custom Java Code Analysis and Refactoring Tools with JaMoPP
Jendrik Johannes - DevBoost GmbH Today, Java code makes up a large part of many software systems. To keep these systems maintainable, extendable and flexible in the long run, constant checking of the consistency of code and other artefacts is necessary. Individual coding guidelines need to be followed, anti-patterns need to be avoided and interfaces need to be used correctly. To save costs and to prevent mistakes during theses tasks, a high degree of automation is desirable. JaMoPP - the Java Model Parser and Printer - addresses these challenges. JaMoPP automatically converts your Java code into an EMF-conformant model. This model can be processed by any EMF-based tool. Additionally, the model can be linked to other files and models for which EMF support exists. For example, BPMN or UML models, property or CSV files or data from databases. With JaMoPP, custom tools for Java code analysis and refactoring can be defined. This way, inconsistencies in the code or between code and other artifacts can be recognised instantly and, if required, repaired automatically. JaMoPP is integrated with Eclipse to provide instant feedback to developers but can also be utilised outside of Eclipse to run checks and refactorings in build scripts or on continuous integration systems. In this talk, we demonstrate the capabilities of JaMoPP and its integration with Eclipse and EMF on multiple practical examples.

Jie Liu - Mirror: Static and Dynamic Analysis of Java Reflection
Reflection, which is widely used in practice, poses a significant obstacle to program analysis. Reflective calls can be analyzed statically or dynamically. Static analysis can be more sound, but may introduce many false reflective targets and thus sometimes make it unscalable. In contrast, dynamic analysis can be precise, but may miss many true reflective targets due to low code coverage. Jie introduces Mirror, the first automatic reflection analysis for Java that reaps the benefits of both worlds. In it's static analysis, a novel reflection-oriented slicing technique is applied to identify a small number of small path-based slices for a reflective call so that different reflective targets are likely exercised along these different paths. This preserves the soundness of pure static reflection analysis as much as possible, improves its scalability, and reduces substantially its false positive rate. In its dynamic analysis, these slices are executed with automatically generated test cases to report the reflective targets accessed. This significantly improves the code coverage of pure dynamic analysis. Jie discusses how the team evaluated Mirror against a state-of-the-art dynamic reflection analysis tool, Tamiflex, by using a set of 10 large real-world Java applications. Mirror detects 12.5% - 933.3% more reflective targets efficiently (in 362.8 seconds on average) without producing any false positives. These new targets enable 5 - 174949 call-graph edges to be reachable in the application code. With Mirror, more reflective targets can be resolved precisely and quickly, rendering a larger part of the codebase to be visible to many analysis tools such as bug detectors and security analyzers. Bio: Jie liu is a PhD student supervised by Prof. Jingling Xue at School of Computer Science and Engineering, University of New South Wales (UNSW). Jie received his B.Eng degree in Software Engineering from Northwestern Polytechnical University (NPU) in 2014. Before joining UNSW, Jie studied in Fudan University as a postgraduate student from 2014 to 2015. Jie started pursuing his PhD in February 2016. Jie's research interests are program analysis, software engineering and programming languages.

Visualizing Java code bases (Andrey Adamovich, Consultant at Aestas/IT)
Code lines are added at high speed? Too many developers? How do you see the big picture? What processes are going on with your large code base? This presentation will show how to leverage existing code analysis tools (Cloc, Structure101, SonarQube) and combine them with data storage (ElasticSearch, Neo4j) and visualization tools (Gource, D3, Inkscape, Kibana) to at least make some sense out of millions of code lines and their history. During his consulting work, author often meets unfamiliar and at the same time large Java code bases that need quick analysis and input for decision making. That’s where visualizations come to into play by helping mining important knowledge directly from the code statistics.

JTeC: A Large Collection of Java Test Classes for Test Code Analysis and Processing
Demo of "JTeC: A Large Collection of Java Test Classes for Test Code Analysis and Processing" Dataset: https://zenodo.org/record/2878368 GitHub repository: https://github.com/JTeCDataset/JTeC Abstract: The recent push towards test automation and test-driven development continues to scale up the dimensions of test code that needs to be maintained, analysed, and processed side-by-side with production code. As a consequence, on the one side regression testing techniques, e.g., for test suite prioritization or test case selection, capable to handle such large-scale test suites become indispensable; on the other side, as test code exposes own characteristics, specific techniques for its analysis and refactoring are actively sought. We present JTeC, a large-scale dataset of test cases that researchers can use for benchmarking the above techniques or any other type of tool expressly targeting test code. JTeC collects more than 2.6M test classes belonging to 31K+ GitHub projects and summing up to more than 431M LOCs of ready-to-use real-world test code.

Nullness Analysis for Java
Google Tech Talks September 17, 2008 ABSTRACT Attempts to dereference null result in an exception or a segmentation fault. Hence it is important to know those program points where this might occur and prove the others (or the entire program) safe. Nullness analysis of computer programs checks or infers non-null annotations for variables and object fields. Most nullness analyses currently use run-time checks or are simply syntactical (as in Eclipse and Idea) or incorrect or only verify manual annotations. We use abstract interpretation to build and prove correct a static nullness analysis for Java bytecode which infers non-null annotations. It is based on Boolean formulas, implemented with binary decision diagrams. Our experiments show it faster and more precise than the correct nullness analysis by Hubert, Jensen and Pichardie. We deal with static fields and exceptions, which is not the case of most other analyses. The result is theoretically clean and the implementation strong and scalable. Speaker: Prof. Fausto Spoto Fausto Spoto is associate professor at the University of Verona, Italy. He took a PhD in computer science from the University of Pisa, where he started working at the static analysis of computer programs. His current interests are related to the analysis of Java and Java bytecode programs. He wrote a tool, Julia, which analyzes Java bytecode programs by using abstract interpretation and presents the results to the user, for verification as well as for code optimisation.

An automatic analysis and detection tool for Java exploits
VB2013 presentation by Xinran Wang Java vulnerability is becoming the most popular exploit vector in the wild. Three zero-day Java vulnerabilities were found in the wild in just the first two months of 2013. Due to the wide deployment of Java in browsers and the high reliability of Java vulnerability, Java exploits are heavily used in numerous infamous exploit kits such as Blackhole and Redkit. According to VirusTotal, the number of Java exploit samples submitted have increased from 8,000 at the beginning of this year to 300,000 at the beginning of March. It is very challenging to accurately identify the vulnerabilities, if any, used in the Java exploit samples. This is not only because of the huge volume of exploit samples, but also the advanced obfuscation technique used. In this paper, we first explain the Java security model and demonstrate several recent zero-day exploits, and show why Java vulnerability is much more reliable than buffer overflow. Several Java exploit samples from popular exploit kits are dissected. We analyse common obfuscation techniques used and show why static analysis is ineffective for analysing Java exploits. Then, we present a dynamic analysis tool. The tool records calls to the Java Core API during the execution of a Java exploit. The recorded API traces are used to identify known vulnerabilities. Furthermore, we propose several heuristics in the tool used to identify zero-day exploits. Finally, we report the results of an experiment based on over 5,000 Java exploit codes and 5,000 benign Java applets collected in the wild. The results shows that the tool identified known vulnerabilities of exploit code with very few positives and false negatives.

Beyond the basics of SonarQube: improve your Java(Script) code even further
(Recorded at Jfokus 2016. http://www.jfokus.com) Beyond the basics of SonarQube: improve your Java(Script) code even further SonarQube is (becoming) more or less the standard tool for managing Java code quality. Unfortunately most developers use it just as a replacement for separate Checkstyle, PMD and code coverage tools. SonarQube is capable of so much more than that, over time SonarQube will even replace the Checkstyle and PMD rulesets with their own ruleset. This presentation will explain a lot of the more advanced features and plugins SonarQube has to offer. The topics include: measuring coverage of a running Java application in an application server, JavaScript plugin, Pitest plugin, compare, measure, code review, hotspots, architectural constraints, package tangle index, PMD rules for unit test quality, incremental analyses and more. Johan Janssen, Info Support Johan is working as a Java architect and competence center Java lead at Info Support. He has been working for various demanding companies where rapidly delivering quality software was very important. Currently he is working in a DevOps team in a big financial institution in The Netherlands as Java architect. He likes sharing his knowledge about Java, continuous delivery, DevOps, software quality and numerous other subjects. Johan regularly writes articles and gives presentations about those subject for instance at JavaOne, JavaLand, JBCNConf, JavaCro, ConFESS and J-Fall.

GenevaJUG Session : Java Static Analysis & Mutation Testing
DIY : Java Static Analysis by Nicolas Peru (french talk) L’analyse statique permet de detecter des bugs et des problèmes dans votre code sans l’executer. Cette présentation vous promet, en toute simplicité, d’ecrire votre propre analyseur pour Java basé sur SonarQube. Pour y arriver il faudra comprendre les challenges d’analyse du langage, du parsing à l’execution symbolique, pour pouvoir coder des vérifications specifiques à vos projets ! Improve your tests quality with Mutation Testing by Nicolas Fränkel and Evgeny Mandrikov (english talk) Unit testing ensures your production code is relevant. But what does ensure your testing code is relevant? Come discover mutation testing and make sure your never forget another assert again. In the realm of testing, the code coverage metrics is the most often talked about. However, it doesn’t mean that the test has been useful or even that an assert has been coded. Mutation testing is a strategy to make sure that the test code is relevant. In this talk, we will explain how Code Coverage is computed and what its inherent flaw is. Afterwards, we will describe how Mutation Testing work and how it helps pointing out code that is tested but leave out corner cases. We will also demo PIT, a Java production-grade framework that enables Mutation Testing on a simple code base. If time allows, a demo will also show how PIT can be integrated with SonarQube. As usual, this session will end up with a buffet provided by our sponsors Hortis | OOSphere | Qim Info | Serial ilem | Kalyss | Sopra Steria

Hybrid Analysis Mapping: Making Security and Java Developer Tools Play Nice Together
Java developers want to write code, and security testers want to break it. The problem is that security testers need to know more about code to do better testing and developers need to be able to quickly address problems found by testers. This presentation looks at both groups and their toolsets and explores ways they can help each other out. Using open source examples built on OWASP ZAP, ThreadFix, and Eclipse, it walks through the process of seeding web application scans with knowledge gleaned from code analysis as well as the mapping of dynamic scan results to specific lines of code in Java developers’ IDEs. Author: Dan Cornell Dan Cornell has over fifteen years of experience architecting and developing web-based software systems. As CTO of Denim Group, he leads the organization’s technology team overseeing methodology development and project execution for Denim Group’s customers.

Java Heap Dump Analysis - VisualVM Tutorial
In this tutorial I show you how to use VisualVM to perform a Java Heap Dump snapshot in a live executing Java application in eclipse IDE. Ahem… Let me ask…First….What is Java VisualVM? Java VisualVM is a tool that provides a visual interface for viewing detailed information about Java applications while they are running on a Java Virtual Machine (JVM), and for troubleshooting and profiling these applications. This includes objects allocated on the Heap, Thread state, Execution environment information, Stack etc. Great for debugging dog slow applications!! Ok cool, now what is a Heap Dump? A heap dump is a snapshot of the memory of a Java Process at a single point in time. This contains data about Java objects, classes in the heap, class, fields, references, class loader names, static content, Thread Stacks etc. And... Why would I create a Heap Dump? There are many, but here are my two favourites. When performing performance analysis on an application, performing a heap dump during certain execution phases will provide you will critical information on the state of the Java Process, such as object allocation on the heap and thread states. Second, when an application crashes due to a Java java.lang.OutOfMemoryError, you can enforce the JVM to perform a snapshot and capture the application’s state via a heap dump. This heap dump will typically be placed into a java_pid*[id].hprof file. You can then load the heap dump file into a visualizer to understand the java applications state – this provides a good insight and clue into why the program crashed. Although if your application is running on a cloud based ephemeral file system this may be tricky. But the majority of applications that require a heap dump for analysis are most likely not in the cloud and rather dedicated high performance data centers.
