Comment 1 Walter Harley CLA 2005-08-12 16:57:56 EDT 
I've not been able to repro this, with latest code, although I have sometimes 
(but not reliably) seen a ClassCastException happening in 
ReconcileWorkingCopyOperation.notifyCompilationParticipants() when I enable and 
disable annotation processing.
Comment 2 Walter Harley CLA 2005-09-27 18:09:25 EDT 
Can repro at least some of the time.  Searching Bugzilla for "checkRemoved" 
yields a list of similar bugs throughout JDT.  Judging by Bug 68993, the answer 
may be a listener on the parent node; I will investigate.
Comment 3 Walter Harley CLA 2005-09-29 17:46:33 EDT 
This is due to Bug 111144.  Not resolving it yet, because we may need to find a 
workaround sooner than that bug can be fixed.

Workaround for bug 106111

This patch is a workaround, that implements (and calls) a renamed, fixed
version of hasProjectSpecificOptions() in the derived class.
Comment 5 Walter Harley CLA 2005-09-30 18:45:49 EDT 
Patch committed.
