JDLabAgent is a dynamic link library which is loaded into the Java Virtual Machine via Java Virtual Machine Debug Interface (JVMDI). The JDLabAgent can be parameterized via config files and logs JVM events (e.g. breakpoints, exceptions).

JDLabStudio is a graphical front-end for the Java Debugging Lab Agent (JDLabAgent). JDLabStudio scans java packages, displays class files and generates JDLabAgent config files. JDLabAgent-traces are used for reconstructing control and data flows.

JDumpViewer is a graphical tool used to analyze Java thread dumps

An Open Source Java Emulation platform for emulating micro computers

Simple - but complete enough - command-line Bash debugger, written as a Bash script. No installation and no root permission required: just download, put every where you prefer and use it. Bash 3 required.

JHeap provides the toolset to help Java developers discover and fix the root cause of memory issues in their applications. JHeap integrates easily with your application server and has been designed to be used in production environments with low overhead.

JLinkCheck is an Ant Task written in Java for checking links in websites. It is not just checking one single page, but crawling a whole site like a spider, generating a report in XML and (X)HTML. JReptator will be its succesor with many more features

JPeek is a graphical tool and library for reflection-based runtime inspection of the object graph in Java.

A viewer to view and analyze the old Java profiler's (java -prof MyApp) output. With the help of this software it is easier to choose the methods to optimize, so you need not optimize all your methods.

JRemoteRun allow execute snippets of java code in running JVM.

Java AS400 RPG source code editor, debugger, IDE.

Jssltrace is a java-based tool, which enables it's user to intercept ssl based communication between two programs. Jssltrace works essentiallly in the same manner as tcptrace (http://www.pocketsoap.com/tcptrace), which is the main inspiration for it.

JSnapshot is an advanced java exception logging, monitoring and analysis tool. It traces thrown exceptions in real-time and logs a snapshot of call stack, variables and objects for every thrown exception. Fully integrated with Eclipse IDE.

The JSwat project has moved to Google Code: http://code.google.com/p/jswat/ -- the contents of the SourceForge project are no longer being updated. Please visit the new site. Thank you.

JTestCase uses XML file to organize multi-testcase data and asserting conditions (action and expected result), and provides a set of easy-to-use methods to retrieve test cases out from XML, and asserts results against those expected ones in data file.

A facility to keep a history of context information during runtime and then dumping it in a separate file when a problem occurs (similar to core dump).

Aligns java-files, which are decompiled by jad

Hugo is a small Android library (and annotation processor plugin) that automatically logs method calls, parameters, return values, and execution time for methods annotated with @DebugLog. Instead of manually adding logging statements everywhere, you simply annotate a method and Hugo injects the logging at compile-time in debug builds, keeping release builds clean. This helps developers gain visibility into method flows, execution timing, and parameter passing without cluttering production code. The annotation doesn’t remain in the compiled class for non-debug builds, so there’s zero runtime penalty in release. Hugo uses bytecode/annotation processing behind the scenes but maintains simple API usage for developers. It’s especially useful during development and debugging phases in large Android codebases where tracing logic by hand would be tedious.

Jassda is a framework that extracts a sequence of method-invokations from a Java application during runtime using the Java Debug Interface (JDI). Jassda provides two modules that operate on the sequence: a logger and a trace-checker

JBCD is an interactive debugger for Java bytecode. It allows a programmer to step through bytecode one statement at time. The tool is indended for people who are writing programs to generate or modify bytecode. JBCD can be used with any Java compiler a

Java-program to read, modify and execute class-files. a real java VM written in java or a decompiler for class-files is possible (and partially working)

A java class assambler. This program assembles java byte code instructions for the JVM, like MASM for the CPU. Knowledge of the java byte code instruction is strongly required.

Utilises the JVMDI (Java Debug API) to produce line coverage reports detailing which lines of code have been executed during a test. Report is produced in XML and may be post-processed via XSLT into a prettier one.

This is going to be a Java Swing Application that will be used as a quick reference for Java API names. It will feature incremental search and filtering so that searching efficiency is improved. It will be very simple and a good way to statistically analyze java api's.
