Java Studio Enterprise 8 errormsg: "Exception occurred in recuest processor

Question

Hello
I recieve this error msg when I try to resolve imports in my code. The detailed message is:
Annotation: Exception occurred in Request Processor
javax.jmi.reflect.InvalidObjectException: Object with MOFID AC2E9F5C-7F2D-11DA-A8AB-0AC5FB43AA77:000000000000313B no longer exists.

     at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:330)
[catch] at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:721)One mystery is that it sometimes works, sometimes not. It is unpredictable. I have reinstalled the program without luck. Can someone help?

Your mdr storage is corrupted. As a quick fix, go into your userdir
then, into var/cache subdirectory and delete the
whole directory 'mdrstorage'. Run the ide - the mdr storage will be built again.
