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
Orome is a tool for automating System or Acceptance tests (also Unit test though this is not the focus) for web-based systems. Orome takes a set of static HTML pages defining a walkthrough of (part of) the systems and tests it against the running system.
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.
Allows JDBC resources to be monitored. You can see when java.sql objects are being opened and closed and can see the line of code where a resource that is still open was originally opened.
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
Bean Bowl is the a fun and useful Java lab, allowing you to play around with Java classes and objects using direct manipulation techniques instead of writing long main() methods. Use it either as an application or as a GUI component framework for you own
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)
xdProf is a tool that captures and analyzes stack traces sent at a fixed interval from Java Virtual Machines in a distributed system. The xdProf client uses a C/C++ Java Virtual Machine Profiling Interface (JVMPI) library and works on many platforms.
httptrace - TCP/HTTP trace utility (for Java or Win32/jview.exe)
Listens on a TCP/IP port, redirects data to another port and writes traces.
Several options (search for patterns, ...).
OpenTNF is a system-level tracing facility for capturing and presenting diagnostic information and performance metrics. Linux/Intel (kernel 2.2.x) is the initial target platform. The OpenTNF project is seeking developers for ports to other platforms.
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/

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.
This project's aim is to create a Eclipse execution flow logger plugin. Thanks to Bil Lewis for his wonderful debugger "Omniscient debugger" http://www.lambdacs.com/debugger/ This is also based on the same idea using ASM library instead of BCEL librar
