Description
Occasionally I get this Exception during a query.
I wasn't able to track it down as it doesn't seem to happen during debugging, so I can't provide mote info at this time.
java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextEntry(HashMap.java:894) at java.util.HashMap$ValueIterator.next(HashMap.java:922) at org.modeshape.jcr.spi.index.provider.IndexProvider.onEachIndexInWorkspace(IndexProvider.java:436) at org.modeshape.jcr.spi.index.provider.IndexProvider$BasicPlanner.applyIndexes(IndexProvider.java:503) at org.modeshape.jcr.query.engine.IndexPlanners$2.applyIndexes(IndexPlanners.java:89) at org.modeshape.jcr.query.optimize.AddIndexes.execute(AddIndexes.java:270) at org.modeshape.jcr.query.optimize.RuleBasedOptimizer.optimize(RuleBasedOptimizer.java:46) at org.modeshape.jcr.query.engine.ScanningQueryEngine.execute(ScanningQueryEngine.java:245) at org.modeshape.jcr.RepositoryQueryManager$1.execute(RepositoryQueryManager.java:172) at org.modeshape.jcr.query.JcrQuery.execute(JcrQuery.java:118) at org.modeshape.jcr.query.JcrQuery.execute(JcrQuery.java:43)
What I can tell is this:
I created indexes in another session but in the same thread just before firing a query that causes the exception.
All Indexes are being defined before any >affected< nodes for that index get created.
Thread.sleep (tested up to 5000) in the Query thread (which is also the index definition thread in this case) doesn't help
Maybe it is related to defining an index on [jcr:uuid] because I didn't get this error previously.
