Description Vaclav Tunka 2015-10-30 05:36:38 EDT
Description of problem:
org.hornetq.core.server.impl.QueueImpl#getConsumers returns the actual Set of consumers, but if another thread modifies this collection while the caller loops through the Set then a ConcurrentModificationException will be thrown. This is possible particularly in management operations that work on the Set of consumers like org.hornetq.api.core.management.HornetQServerControl#closeConsumerConnectionsForAddress.
