Open Source Java Debuggers for Desktop Operating Systems

MinGW: A native Windows port of the GNU Compiler Collection (GCC), with freely distributable import libraries and header files for building native Windows applications; includes extensions to the MSVC runtime to support C99 functionality. All of MinGW's software will execute on the 64bit Windows platforms.

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.

ALF, The Automated Logging Framework, is a native logging framework for Java with the unique advantage of supporting automated method tracing. This platform-independent library allows developers to debug their applications quickly without adding code

BeanClipse is a NetBeans plugin for Eclipse: NetBeans runs embedded within the Eclipse platform as a plugin offering the best of both worlds to Java developers. May be just a joke ;-) .... Check also it's twin at : http://sf.net/projects/netclipse

Coffeetronix is the fast and simple Java UML workbench. It parses your java sources and creates an instant UML classdiagram.

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.

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.

Adapted from eclipse cde elf tools, enables java to generate dwarf symbols and register compiled method with gdb-jit interface. It is intended for JikesRVM/MRP to use, and currently has one provider interface.

FastAOP is an very high performant AOP (Aspect Oriented Programming) framework for java. The framework was initially developped to support performance profiling and monitoring for large J2EE applications with nearly no runntime overhad. Announcement: jp-mobile and fastAOP will go mobile, please visit jp-mobile (GWT based) website at: http://code.google.com/p/jp-mobile/

Modern software systems and application are commonly written in multiple languages, include scripting engines, and are frequently build on multiple specialized frameworks and middleware for a considerable diversity of runtime environments. The latest influencing update in development paradigm is the application of multicore processors. This projects is aimed to unify the required trace and logging output and integrate into debugging environments. The target is to provide general development, test, and production support of software environments based on multiple programming languages for distributed multicore environments.
