patch
This patch creates a copy of the resources list in a thread safe manner and works on it, so that we don't get the ConcurrentModificationException desicribed in the bug.
Tested with a large workspace (100+ projects) with various scenarios including restarting workspace and letting 'Initializing Java Tooling' complete. Didn't see the issue anymore.
approved * Explain why you believe this is a stop-ship defect. Or, if it is a "hotbug" (requested by an adopter) please document it as such.
This defect causes user workspaces to get into an inconsistent state, and surfaces the exception to the user (in the log).
* Is there a work-around? If so, why do you believe the work-around is insufficient?
Restart the product and continue, if the exception is not seen after 'Initialize Java Tooling'
* How has the fix been tested? Is there a test case attached to the bugzilla record? Has a JUnit Test been added?
Tested with various scenarios including several restarts using a 100+ project workspace.
* Give a brief technical overview. Who has reviewed this fix?
This fix has been reviewed by Chuck Bridgham.
* What is the risk associated with this fix?
No known risks.

Build Identifier: 321 I don't have a way to reproduce this consistently. I'm working in a workspace with ˜100 projects and I sometimes get the below error as the workspace builds for the first time when I open that workspace.
