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.

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)

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.

Java tool for searching classpath for resources such as class or files. Drag and drop interface for add new jars to your search path. Useful for resolving those class not found problem such as java.lang.ClassNotFoundException and java.lang.NoClassDefFoun

JAVA Program to Sequence Diagram Generator. This tool tries to help on analysing and understanding the behavior of the code when developping JAVA applications by generating the respective Sequence Diagram automatically at program execution.

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.

A Java class library for logging, tracing, warnings, errors, asserts, etc with runtime configurable formatting and event filtering. This project is no longer maintained.

This project is a java web application developer toolbox. It is among other, a simple and powerful framework which does not require dealing with XML files. It also provides a lot of other features, such as a DB abstraction layer, a nice javadoc doclet, a

JavaShark is a new way to view/trace/analyze JVM applications. It's like an advanced debugger with Groovy support. And the most important - now you can share your knowledge about any system with people around the world - just share your handlers(breakpoints) bundle. Just imagine - you connect to the remote JVM, attach handlers bundle and now you know much more than any logs could ever give you. It's free and open source under MIT license. All debug power is in your hands now in a handy and cool way.

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

A highlevel API to instrument Java bytecode. Jiapi can be used to modify bytecode of a Java class before it is loaded into a virtual machine.

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

Jour is designed to simplify the use of Javassist for processing multiple classes. In short Jour is simple Aspect Oriented Programming AOP framework on top of Javassist.

Jylog is a (JPDA) Java Platform Debugger Architecture based logger, Jylog eliminates the need for writing any log statement in the program. one can define the logging information using Jylog swing GUI and Jylog extracts the information from JVM at runtime

A KDE binary executable/object file viewer (presently supporting ELF, to support others eventually)

KBOX is a MVC model2 frame work. It helps you create an extensible development environment for your application, based on published standards and proven design patterns.

KScriptDbg4 is a GUI to Perl & Python script debugger. This GUI is the result of the port to KDE4 / Qt4 of Protoeditor, a project by Thiago Silva, based on release 1.1beta3. It offers the main functions of a debugger : set breakpoints, run the script step by step, enter a function, step outside a function, display global and local variables, watch for variables or expressions ... Local or remote scripts can be debugged; remote debugging uses the DBG protocol through libraries provided by the package. Main improvements to Protoeditor are : the stack is displayed in a separate page and the breakpoints are saved in the global config file in order to be restored at the next session on the same script. KDE4, Qt4 & Cmake are required to build this GUI; a 'configure' script & a Makefile are provided to help building KScriptDbg (see INSTALL for details) A '.tar.xz' & a source RPM pkg. are also available Changelog v1.2.2: Highlight changed values of global & local variables

KerX (Kernel eXplorer) provides a simple way for reading the very low-level data structures of the OS (GDT, IDT, TSSs, Page-Tables, Page-Directories, etc...)
