jBixbe lets you debug Java applications on the conceptual level of the Unified Modeling Language (UML) at which they are designed and makes it possible to find not only simple bugs but also weaknesses and inefficiencies in application design. It shows the big picture of your application so you can recognize classes and objects, and their relationships and interaction. Different view levels support top-down debugging and simplify debugging of multi-threaded applications. Source code debugging has been fully integrated into the object-oriented visualization.
a standalone Java debugger built on top of the standard JPDA (Java Platform Debugger Architecture). JDebugTool features a graphical and intuitive Java Swing GUI, and integrated Java Help
(commercial) JIRA Client is a desktop client for the Atlassian JIRA issue tracking system. JIRA Clients allows users to work with issues anywhere and save time by using an interactive interface for issue tracking. Key features: an offline mode with later synchronization; a three-pane main window that shows filters with counters, a list of issues, and details of a selected issue; a query builder that allows you to build any filters with and, or, and not operations; and query counters, which immediately show how many issues satisfy any given filter.
an experimental new tool for logging the trace of Java method calls and method returns together with their parameters and results by using the JVMDI interface
JMemProf is a live Java memory profiler suitable for deployment in web containers such as JBoss, Tomcat and others. JMemProf allows you to retrieve memory profile information while your application is running.
(commercial) a Java monitoring system that allows you to control and supervise your java application. The main focus is the logging subsystem, which allows you easy online configuration and access to log messages
enables you to understand how much space the packages and classes consume in your Java class path. And it can help you find class paths problems
(commercial) a Java unit testing tool that automatically tests any Java class, JSP, or component without requiring you to write a single test case, harness, or stub. With the click of a button, Jtest automatically tests code construction (white-box testing), tests code functionality (black-box testing), and maintains code integrity (regression testing)
a static Java source code analyzer that detects locking and threading issues, performance and scalability problems, and checks complex contracts such as Java serialization by performing type, data flow, and lock graph analysis

MoMEUnit is an instance of the xUnit architecture for unit testing of J2ME applications. It is derived from the JUnit framework. It is only CLDC 1.1 compliant. It overcomes the lack of a reflection API in the J2ME MIDP API and supports main features of the JUnit framework such as ease of development and running of tests, sharing of fixtures among different tests, the ability to perform simultaneous test runs, and much more. The results of tests are displayed with a progress bar, statistics, and lists of failures or errors with detailed messages for each test.
