Sorry - this was in another context (I was also running a 2.1 build worksapce). This happened there during save and I was probably using I20040413 at that time.

I am usin the integrtion build I20040428 and I get this relative often (every 20 minutes or so) "Problems occurred during save." java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextEntry(HashMap.java:782) at java.util.HashMap$KeyIterator.next(HashMap.java:818) at org.eclipse.jdt.internal.core.JavaModelManager.saving (JavaModelManager.java:1410) at org.eclipse.core.internal.resources.SaveManager.executeLifecycle (SaveManager.java:308) at org.eclipse.core.internal.resources.SaveManager$1.run (SaveManager.java:129) at org.eclipse.core.internal.runtime.InternalPlatform.run (InternalPlatform.java:599) at org.eclipse.core.runtime.Platform.run(Platform.java:543) at org.eclipse.core.internal.resources.SaveManager.broadcastLifecycle (SaveManager.java:141) at org.eclipse.core.internal.resources.SaveManager.save (SaveManager.java:1323) at org.eclipse.core.internal.resources.DelayedSnapshotJob.run (DelayedSnapshotJob.java:42) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:66)

Now cloning the HashMap before iterating over it. Also protected other access to the 'containers' field. Note for those who worried, the consequence of this bug were null.
Verified for 3.0 M9 with build I200405180816.
