> Key: QPID-7050
> URL: https://issues.apache.org/jira/browse/QPID-7050
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: 0.32, qpid-java-6.0, qpid-java-6.1
> Reporter: Alex Rudyy
> Fix For: qpid-java-6.1

>
> The failure of test BDBHAVirtualHostNodeRestTest.testIntruderProtection
> reviled that BDB HA VHN close could be delayed by REF close waiting for
> state change executor shutdown when change executor shutdown is performing
> task for state change event.
> On state change state change executor invokes
> BDBHAVirtualHostNodeImpl.EnvironmentStateChangeListener#stateChange and waits
> for operation to finish. If operation invokes configuration thread to do the
> work and waits for its finish and, at the same time when, REF#close is
> performed in config-thread, for example, because of intruder protection, the
> two threads block each other.
> Config thread performing in REF#close() is waiting for state change thread
> to finish and state change thread is waiting for config thread to finish
> submitted state change task.
> At least one thing could be changed to fix the issue:
> Close of existing VH is performed in broker config thread. It should be
> changed to use VHN config thread. I am not sure whether changing of
> config-thread would be sufficient to fix the problem.
