Description
In StateConsumerImpl.onTopologyUpdate(...) the transfersBySource.keySet() is iterated while under some conditions transfersBySource.remove(...) is called. As the iterated keySet is backed by the HashMap itself modifications during iteration are not permitted and I got
java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextEntry(HashMap.java:894) at java.util.HashMap$KeyIterator.next(HashMap.java:928) at org.infinispan.statetransfer.StateConsumerImpl.onTopologyUpdate(StateConsumerImpl.java:215) at org.infinispan.statetransfer.StateTransferManagerImpl.doTopologyUpdate(StateTransferManagerImpl.java:186) at org.infinispan.statetransfer.StateTransferManagerImpl.access$000(StateTransferManagerImpl.java:58) at org.infinispan.statetransfer.StateTransferManagerImpl$1.updateConsistentHash(StateTransferManagerImpl.java:117) at org.infinispan.topology.LocalTopologyManagerImpl.handleConsistentHashUpdate(LocalTopologyManagerImpl.java:194) at org.infinispan.topology.CacheTopologyControlCommand.doPerform(CacheTopologyControlCommand.java:165) at org.infinispan.topology.CacheTopologyControlCommand.perform(CacheTopologyControlCommand.java:137) at org.infinispan.topology.ClusterTopologyManagerImpl$3.call(ClusterTopologyManagerImpl.java:554) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:722)
