Description Frederic Fusier CLA 2006-07-04 10:49:55 EDT 
Using JDT/Core v_703.

While starting my test workspace with breakpoint on NullPointerException, debugger stops at ClassValidation.validate() line 61 with status == null.

Here's the stack trace:
ClasspathValidation.validate() line: 61	
DeltaProcessor.resourceChanged(IResourceChangeEvent) line: 1867	
DeltaProcessingState.resourceChanged(IResourceChangeEvent) line: 369	
NotificationManager$2.run() line: 282	
SafeRunner.run(ISafeRunnable) line: 37	
NotificationManager.notify(ResourceChangeListenerList$ListenerEntry[], IResourceChangeEvent, boolean) line: 276	
NotificationManager.broadcastChanges(ElementTree, ResourceChangeEvent, boolean) line: 148	
Workspace.broadcastBuildEvent(Object, int, int) line: 240	
AutoBuildJob.doBuild(IProgressMonitor) line: 142	
AutoBuildJob.run(IProgressMonitor) line: 208	
Worker.run() line: 58	

Not sure, but it seems that it is due to synchronized block just before. When perProjectInfo object is locked by another thread, then status is not set...

Looking at the source, I don't understand how this can happen. Please reopen if you have steps to reproduce.

Closing due to lack of information
Comment 3 Denis Roy CLA 2009-08-30 02:09:44 EDT 
As of now 'LATER' and 'REMIND' resolutions are no longer supported.
Please reopen this bug if it is still valid for you.
