> org.apache.activemq.artemis.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.apache.activemq.artemis.api.core.management.ActiveMQServerControl#closeConsumerConnectionsForAddress.
