This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
While editing Java source code, I found that the "find usages" option seemed to have stopped working. After being unable to find a workaround, I decided to close and restart NetBeans to see if that would fix the problem. Upon restart, I received a NullPointerException: A java.lang.NullPointerException exception has occurred. Please report this at http://www.netbeans.org/issues.html, including a copy of your messages.log file as an attachment. The messages.log file is located in your /home/kjn/.netbeans/4.1/var/log folder. After clicking "OK" in response to this message, NetBeans remained in an unusable state. Subsequent restart attempts have also failed.
Created attachment 23369 [details] Log file containing initial error
Created attachment 23370 [details] Log file from subsequent restart attempt
Deleting and re-installing the mevenide plugin appears to have corrected the problem.
The error with "find usages" appears to be persisting.
