Open Source Java Debuggers

BT-Sim is a BlueTooth simulator on a HCI level. The project alows to develop and test BT applications without using real BT hardware. It works in particular with PalmSource's Palm OS Simulator.

Java IDE, project support, build, debugger, grep.

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

Bash made easier: A simple IDE / Debugger for writing, debugging, and executing single commands and short scripts. If you are a struggling occasional user of Bash, or would be a user if it weren't so difficult to get started, then this program will help. Runs on Linux or Windows Subsystem for Linux.

NetworkTools has 2 components: A protocol analyzer which plays a TCP client or server or pipeline, which sits between a client and server and shows how they communicate. A port scanner can scan a range of IP addresses and ports. See screenshots.

MakeLogic Tail is an advanced "tail -f" command with GUI. It needs JRE 5.0, hence it is 'Tail for Windows', Linux or 'Tail for Mac'. It shows the last few lines of a growing log file in real time. Provides many more easy to use features. Try it!

NetTool is a developer tool for monitoring and manipulating application-level network messages, particularly useful for debugging web applications and web services. There are two components to NetTool: the HTTP Client, and the TCP Tunnel.

An eclipse plugin providing tail in view component.

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.

Seksen is a GUI based 8086, 80186 emulator and debugger in Java.

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

It is a Process Monitoring Toolkit with the ability of Extend. E.g. You can use it to monitor a specified process. And set a triger like (over 50MB mem use) then do something like (report to DB).

Avrora is a suite of tools for analyzing and debugging programs for AVR microcontrollers. It has support for a sensor platforms such as Mica2 and MicaZ, allowing wireless network simulation and allows dynamic instrumentation and static analysis.

Debugger for Bash version 3(Bourne again shell). Plugin for Eclipse. Will only work with shell script editor ShellEd.

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

Bugkilla is a set of java tools for the functional test of J2EE Web Applications. Specification and execution of tests will be automated for web front end and business logic layer. One goal is to integrate with existing frameworks and tools.

Yet another logger. Take a close look at it: It is very easy to use, very unified and extendable. You may attach your favourite set of loggers to this logger, and you still use only one API! This Java logger is used throughout the COMJAT.NET systems.

CoDeK - Java Concurrent Development frameworK is a very simple, open-source, academic java library aimed to help the development of Java multi-threading concurrent applications.

This is a student project designed to compete in the 2010 IEEE Computer Society Student Competition: http://www.computer.org/portal/web/competition/2010competition The Code Red architecture is designed for extremely lower power environments, like distributed sensor networks. Included is a design of that architecture, a Java-based simulator, an implementation (without vector instructions) designed as a Logisim circuit (http://ozark.hendrix.edu/~burch/logisim/), and more. The name "Code Red" comes from our team name, the Red Team. Since the competition dictated a small team size, our professor split the class and gave each group a color. We liked the name "Code Red" and chose it to represent our team and school's color (UMass' official color is Maroon.) Only later did we realize that "Code Red" was the name of an unrelated computer worm from 2001.

CorbaTrace is a helpful tool for tracing communications beetween Corba objects. Once CorbaTrace is installed, remote calls are intercepted and informations are stored in XML files. So, you will be able to apply filters and get XMI files to see the commu

Cricket Cage automatically creates JUnit TestCases for repeatable bugs and test scenarios. Include Cricket Cage's AspectJ code to install a code generator, then run the program to generate the TestCase. Finally, add the test case to your build.xml.

Follow is a simple Java application which allows a user to monitor several log files concurrently. The source for this project is now being maintained at http://hallwaytech.github.com/follow

GDBServer Extender（gdbx）顾名思义就是为GDB调试扩展一些本来没有的功能。例如线程（任务）感知调试（OS Aware）、线程（任务）堆栈检查等。支持FreeRTOS、eCos。支持OpenOCD、J-Link、QEMU。支持Cortex-M、i386。 请移步https://code.csdn.net/zoomdy/gdbx获得更多内容。

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.

JCola is a file tailing application written in Java Swing. This multithreaded application can tail an unlimited amount of logfiles concurrently and simulates "tail -f" with much more functionality.
