Description Gunnar Wagenknecht CLA 2003-01-05 18:22:32 EST 
Build: M4

I got the following exception in certain situations since today. It worked ok 
all the time before.

Today I created 2 features and 2 more plug-ins for preparing my application for 
deploying. I get this error on a fresh created workspace.

After restarting Eclipse it works.

Comment 1 Dejan Glozic CLA 2003-01-11 14:51:11 EST 
This is an 'old friend' :-). Moving to JDT Core for comments: we were told that 
this problem will be addressed after M4. How far along are you?
Comment 2 Philipe Mulet CLA 2003-01-13 05:20:43 EST 
This unfortunately did not get addressed in M4 (too many changes too close to 
the milestone). Fix should be part of next integration build.
