I've seen a few "concurrent modification exceptions" lately. Just thought I'd report. The only think I was doing was opening the b3 aggregator editor, on Juno's "simrel.b3aggr" file. The version I have installed is from 8/16. b3 Aggregator Editor (Incubation) 0.2.0.v20110816-1008 org.eclipse.b3.aggregator.editor.feature.feature.group Eclipse b3 Project = = = = !ENTRY org.eclipse.core.jobs 4 2 2011-09-19 21:40:06.553 !MESSAGE An internal error occurred during: "Loading p2:http://download.eclipse.org/modeling/emft/mwe/updates/releases/R201108020809/mwe2lang". !STACK 0 java.util.ConcurrentModificationException at org.eclipse.emf.common.util.AbstractEList$EIterator.checkModCount(AbstractEList.java:762) at org.eclipse.emf.common.util.AbstractEList$EIterator.doNext(AbstractEList.java:710) at org.eclipse.emf.common.util.AbstractEList$EIterator.next(AbstractEList.java:696) at org.eclipse.b3.aggregator.p2view.impl.RepositoryBrowserImpl.getRepositories(RepositoryBrowserImpl.java:261) at org.eclipse.b3.aggregator.p2view.provider.RepositoryBrowserItemProvider.notifyChanged(RepositoryBrowserItemProvider.java:245) at org.eclipse.emf.common.notify.impl.BasicNotifierImpl.eNotify(BasicNotifierImpl.java:380) at org.eclipse.b3.aggregator.p2view.impl.RepositoryBrowserImpl$NotifyDispatcher.notifyChanged(RepositoryBrowserImpl.java:69) at org.eclipse.emf.common.notify.impl.BasicNotifierImpl.eNotify(BasicNotifierImpl.java:380) at org.eclipse.b3.aggregator.impl.MetadataRepositoryReferenceImpl.setMetadataRepositoryGen(MetadataRepositoryReferenceImpl.java:732) at org.eclipse.b3.aggregator.impl.MetadataRepositoryReferenceImpl.setMetadataRepository(MetadataRepositoryReferenceImpl.java:720) at org.eclipse.b3.aggregator.p2.util.MetadataRepositoryResourceImpl$AsynchronousLoader.run(MetadataRepositoryResourceImpl.java:131) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54) !ENTRY org.eclipse.core.jobs 4 2 2011-09-19 21:43:37.749 !MESSAGE An internal error occurred during: "Loading p2:http://download.eclipse.org/datatools/downloads/drops/M_updates_1.9". !STACK 0 java.util.ConcurrentModificationException at org.eclipse.emf.common.util.AbstractEList$EIterator.checkModCount(AbstractEList.java:762) at org.eclipse.emf.common.util.AbstractEList$EIterator.doNext(AbstractEList.java:710) at org.eclipse.emf.common.util.AbstractEList$EIterator.next(AbstractEList.java:696) at org.eclipse.b3.aggregator.p2view.impl.RepositoryBrowserImpl.getRepositories(RepositoryBrowserImpl.java:261) at org.eclipse.b3.aggregator.p2view.provider.RepositoryBrowserItemProvider.notifyChanged(RepositoryBrowserItemProvider.java:245) at org.eclipse.emf.common.notify.impl.BasicNotifierImpl.eNotify(BasicNotifierImpl.java:380) at org.eclipse.b3.aggregator.p2view.impl.RepositoryBrowserImpl$NotifyDispatcher.notifyChanged(RepositoryBrowserImpl.java:69) at org.eclipse.emf.common.notify.impl.BasicNotifierImpl.eNotify(BasicNotifierImpl.java:380) at org.eclipse.b3.aggregator.impl.MetadataRepositoryReferenceImpl.setMetadataRepositoryGen(MetadataRepositoryReferenceImpl.java:732) at org.eclipse.b3.aggregator.impl.MetadataRepositoryReferenceImpl.setMetadataRepository(MetadataRepositoryReferenceImpl.java:720) at org.eclipse.b3.aggregator.p2.util.MetadataRepositoryResourceImpl$AsynchronousLoader.run(MetadataRepositoryResourceImpl.java:131) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)
I do see, now, there is an 8/18 version ... maybe this has been fixed already? ... so, I installed that 8/18 version. b3 Aggregator Editor (Incubation) 0.2.0.v20110818-1257 org.eclipse.b3.aggregator.editor.feature.feature.group Eclipse b3 Project
I see I've opened this bug several times. Even though this is the older bug, will mark as dup of new bug. *** This bug has been marked as a duplicate of bug 442191 ***
[Bookkeeping change only. Moving bugs to the new "home" of aggregator, CBI. Made no changes to assignee's for closed bugs, even though some were old inbox.]
