> Key: QPID-6671
> URL: https://issues.apache.org/jira/browse/QPID-6671
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Reporter: Keith Wall
> Assignee: Alex Rudyy
> Fix For: qpid-java-6.0
>
> Attachments:
> TEST-org.apache.qpid.test.unit.ack.RecoverTest.testOrderingWithSyncConsumer.txt,
>
> potential-fix-for-NoSuchElementException-on-concurrent-vhn-close-in-broker-config-thread-and-connection-close-in-vh-io-pool.diff
>
>
> The Broker failed during shutdown of test
> RecoverTest#testOrderingWithSyncConsumer. It appears that the deregistration
> was show how attempted after the virtual host was unregistered from its
> parent. This should not be possible: the virtual host should await its
> associated connections closing *before* allowing itself to close, therefore
> the VH should not yet be deregistered from the VHN.
