The JDIC Project has posted an early access release of the Tray Icon API, "a set of interfaces for creating tray icons on the desktop. A tray icon can have a caption (text), an icon, and a menu associated with it. It can also have a tool tip that is displayed when the mouse hovers over the tray icon. To get animation in the notification tray, use an animated GIF for the icon. Tray menus are Swing menus, which enables them to contain icons (unlike Windows and Gnome tray menus) and have either a cross-platform look and feel or the system look and feel." The Tray Icon API is published under the LGPL.

Version 2.3 is API and protocol backwards compatible with previous 2.x releases. New features in this release include:
Joey Gibson has written an Ant task that makes "it a little easier to work on a project using both Ant and Eclipse. What this task does is read the .classpath file that Eclipse uses to maintain your project's classpath, combines that with your Eclipse preferences to expand classpath variables and then creates a path-like structure in your Ant project that you can compile against." It relies on JDOM.
Diomidis Spinellis has released UMLGraph 2.5, an open source (BSD license) tool for declaratively specifying UML diagrams.

A doclet converts this into a Graphviz diagram that can be easily converted to Postscript, GIF, SVG, JPEG, etc. Version 2.5 allows the the swimlanes object in a sequence diagram to show nested object invocations.
