Product Version: NetBeans IDE Dev (Build 070723) Java: 1.6.0_02; Java HotSpot(TM) Client VM 1.6.0_02-b05 System: Linux version 2.6.16-1.2122_FC5 running on i386; UTF-8; en_US (nb) After a 'gray' java hint tooltip was shown after click on an java error hint it was not closed and remained opened in running ide and whole system. Only exiting of ide helps. I cannot reproduce it.
Need thread dump and messages.log
I cannot provide the logs. I have seen it only once. You can close it as unreproducible.
There is no additional info provided, so I guess it was really only a random problem - closing as WORKSFORME
