[Bug swing/24022] New: JTree - BasicTreeUI.paint throws AssertionError with JUMP

[WBaer at gmx dot de]

Hi,

my last bug reports about JUMP were quickly resolved by Lillian.
However there seems still to be some wrong logic how classpath
paints its JTree which is shown by an AssertionError during JUMP
startup. Tested with jamvm/classpath cvs 22/09/05

Exception during event dispatch:

I am sorry this time I cannot prepare a simple testcase. I can
only provide you with the links to the program and a modified
jar which works around an error during startup.

Download the binary/source JUMP distribution from
http://www.jump-project.org/project.php?PID=JUMP&SID=DOWN

Unzip and modify the provided JUMPWorkbench-unix.sh startup
script to use jamvm with Graphics2D enabled.

You will see an error during startup due to unimplemented
awt stuff. A modified jar which works around that problem
is uploaded to http://www.home.uos.de/wbaer/downloads/jump-1.1.2.jar

Put this one in the lib dir instead the original one.

Regards,

Wolfgang
