Open Source Java Compilers for BSD

We extend the Eclipse IDE with tools for development in Haskell, a functional programming language, providing support for a wide range of tools (compilers, interpreters, doc tools etc.) in a coherent, convenient and configurable environment.

Java Decompiler, Disassembler and Bytecode debugger. Decompiler supports Java 5 (e.g. generics, for-each loops etc). Debugger allows user to step through each bytecode and view program state. Contains Swing GUI.

Java AS400 RPG source code editor, debugger, IDE.

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.

ObjectScript is a general purpose object-oriented programming language. It is designed to be simple to learn, easy to use, yet still powerful, combining the convenience of an interactive interpreter with many of the features of Java

GNUDE is a complete suite of GNU C, C++, Fortran, and Java Cross Compilers, and the GDB CPU Simulator and Debugger for embedded microprocessor applications development. Targets development for ARM7, ARM9, and XScale applications.

This sourceforge site for the project is now DEPRECATED and not updated. All current work and new releases are on github: https://github.com/OpenJML/OpenJML. The Java Modeling Language (JML) is a behavioral interface specification language that can be used to specify the behavior of Java modules (as in design by contract -- DBC). It has many tools to do assertion checking, unit testing, etc. The principal current tool of the project is OpenJML -- cf. https://www.openjml.org, with binary downloads from https://github.com/OpenJML/OpenJML/releases/latest

Plugins for Maven 1.x (http://maven.apache.org/maven-1.x/) - manage all aspects of your project (tests, docs, distribution) from a single project descriptor! This project provides plugins that are not bundled with Maven due to differing licenses.

Introspect on running programme, view and alter object fields and methods. Edit the code of any method at runtime; apply the changes to any combination of objects, such as an array, or a complete class. Complete rewrite underway available Jan 2007.

Tools for enforcing projects architecture specifications. Identification of "patterns" based on nomenclature rules. Validation of conformance to architecture rules. Query-based investigation. Statistics. Metrics.

jbytecode is a Java bytecode disassembler/assembler written in Python. Dissasembly code is aligned with Java bytecodes in the class file so modification and re-assembly is always possible, even when class is obfuscated.

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

To develop a plug-in for eclipse (eclipse.org) allowing for seamless Eiffel Development using the SmartEiffel (smarteiffel.loria.fr) compiler and the ELJ (elj.com) tools.

ExStudio is a set of development tools for the "Ex" virtual machine. It includes the vm itself, a compiler, an assembler and a debugger.

Tho goal of this project is to provide an integrated development environment for developing (x)Harbour applications on various platforms.

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)

JavaCET is an API wrote in Java that allows to analyze Java source code and libraries, and control its execution and its trace in an integrated and comprehensible object-oriented way. It allows backwards execution.

JodeEclipse is a plugin for integrating the Jode Java Decompiler with the Eclipse IDE.

This project aims to implement an LC2/LC3 assembler and simulator for the Linux and Windows platforms.

A complete Parallax Propeller debugger/simulator for development of assembler code, with built-in editor and compiler. In runs under Java v1.5 or better.
