Comment 2 Tomas Danek 2008-09-05 11:39:52 UTC 
...i can reproduce consistently -> P1:(

what i did:
- have a freeform project (JFreechart), during setup i binded targets + set up classpath for sourceroot
- built project and javadoc to be able to set up dependency for testroot and project output
- project properties - added just built jar to classpath for testroot, on output panel browsed for javadoc folder
- click ok to save -> deadlock

I am able to reproduce constantly, since project properties are not saved, and when i restart (dead) ide, i can
reproduce again by trying to modify project properties again...
Comment 3 Tomas Danek 2008-09-05 12:31:36 UTC 
BTW what matters is the adding the built jfreechart.jar to testroot classpath..
