Dynamic Interactive Views For Reverse Engineering. Div/er is a set of Eclipse Plugins that aid developers in understanding software. It uses dynamic analysis and reverse engineering to offer views and filters that aid comprehension and discovery.

Glassbox is an automated troubleshooting and monitoring agent for Java apps that diagnoses common problems with one-click. Drop in a .war file from http://www.glassbox.com and find out what's wrong with your existing web apps, without any code chang

ASGMemProf is an exact, bytecode instrumenting memory profiler for Java EE, relying on a novel scheme - memory accounts.

This is a research project aimed at providing tools to help developers capture and visualize what is actually happening when your program executes. And hopefully make debugging an easier, quicker and less painful process.

Elvyx is a tool designed to monitor and profile the jdbc activity on java projects. This jdbc profiler has a server with a built-in db and a client to improve the experience.

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

JRemoteRun allow execute snippets of java code in running JVM.

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.

Jdptool is a debug and profiler tool which based on JPDA; It provide both swing based and browser based GUI. It has sophisticated debugger without user interfere. It also provide profiler to memory usage and threads with numerous new feature

Madmap is a tool to help analyze java heap dumps. New in v1.1 it supports hprof ascii and now binary dumps collected with jmap. It helps find memory leaks by showing the live set and automatically calculating which objects retain the most heap size.

Sock4Log is a simple java xml serwer. Sock4Log will listen for client connections on the specified port number. It is created for retrieving xml log data from Flash Swf aplications which are using XmlSocketConnection.

Yet Another Java Profiler (YaJP) is a profiler tool that uses the JVMTI interface. It can be used to selectively trace a java program and store this information in a compressed logfile. This logfile can then later be analyzed using the same tool.

Libinstrument is a complete and easy way to do custom function instrumentation for C/C++. The project comes ready with classic applications of instrumentation, such as AOP (Aspect Oriented Programming), Concern and Side Effect injection, stack tracing, exception tracing, basic time profiling, callgraph profiling and other. A GC (Garbage Collector) module is also under development. Libinstrument is highly portable and decoupled. The project comes with a CMake build system, integration with IDEs (CLion, Eclipse e.t.c) is straightforward. Using lazy algorithms there is virtually zero overhead in benchmarks and minimum overhead in execution time. Libinstrument tries to be as non-intrusive as possible, while trying to help the developer offering basic reflection. There are Unit Tests for each class and method, testing is driven with CTest.

Insight, the analysis TechTool for developers is a platform independent tool for viewing & analying run time meta data of applications. It aids in trouble shooting problems, and aids the developer in every day work through very advanced log analysis.

FProfiler is a Java Profiler using log4j. Its very fast because it inserts the needed instructions into the byte-code of the class. It can be used to find "Hotspots" in Java programs, libs and servlet environments simply every Java class.

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.

This is a dynamic slicing tool for Java programs. The tool modifies the Kaffe virtual machine to collect the execution trace, and compress the trace on-the-fly. Please proceed to the tool's website http://jslice.sourceforge.net/ for download.

This project aims at being the spearhead of logging tools. It will integrate with existing logging frameworks and will incorporate unique features to maximize speed and usability.

SFN is a simple and modular instrumentation agent for Java.

Swing Spy is java based Swing/AWT spy agent that prints the widget under the cursor (like Spy++ for Windows/MFC and SWT Spy for Java-SWT). Download from the homepage: http://www.nenoff.com/swingspy/

inspectorJ is a cross platform java profiler with a graphical client that allows for profiling remote jvms. inspectorj is pre-alpha and is currently under development.
