Comment 1 Valentin Yerastov CLA 2011-03-14 15:31:55 EDT 
This happens because we try to open java.lang.Exception in the artifact editor, that can not be done in principle.

My suggestion to solve this problem - is to change the method 
org.eclipse.tigerstripe.workbench.ui.internal.views.explorerview.actions.TSOpenAction.openEditor (Object, IWorkbenchPage)
so that method will check the resource availability for the opening artifact or not (getAdapter (IResource.class) == null), and if not then do not open and does not throw an exception, because this situation is quite normal.
Also, if a resource for artifacts is not available, disable the link extends.

I solved the problem by making 'java.lang.Exception' artifact read-only
