DrJava

DrJava has been significantly improved since the
last freshmeat announcement. The major
enhancements include integrated unit testing
support through JUnit, an integrated debugger
which complements the Interactions pane, a
Preferences window for configuring DrJava, and
online documentation. A large number of bugfixes
and new features have also been included.

A fix for a bug where available compilers (at known locations) are not always detected at startup, and converting toolbar button labels to text to make things easier for beginners.

Improvements were made to the interactive pane history. Right/left arrow keys no longer let you move past the area in which you can type. Pressing the down arrow at the end of the history clears the input line. The history is capped at 500 lines.

A new ability to scroll down to the end of the history in the interactions window and get back to a blank line, and fixes for initial positioning of small screen sizes (including corrections for the Mac OS menubar).

Prompting the user to select a compiler at startup if none is auto-detected, and starting the main window centered on screen.
