> Project: Qpid
> Issue Type: Bug
> Components: Broker-J
> Affects Versions: qpid-java-broker-7.0.3, qpid-java-broker-7.1.0
> Reporter: Alex Rudyy

>
> {{SystemNodeRegistry}} of deleted {{VirtualHost}} is still referenced after
> virtual host node deletion. It prevents VHN/VH garbage collection. The
> reference to registry is hold by
> {{TrustStoreMessageSourceCreator$TrustStoreChangeListener}} which is
> registered on broker as part of invocation
> {{TrustStoreMessageSourceCreator#register}}.
> The user impact is minimalistic as it is not expected that virtual host nodes
> are often created and deleted in production environment.
> Broker restart should resolve the issue.
> Steps to reproduce:
> # create BDB HA virtual host node
> # delete BDB HA virtual host node
> # collect heap dump and check references to deleted virtual host node
> {noformat}
> select * from
> org.apache.qpid.server.virtualhostnode.berkeleydb.BDBHAVirtualHostNodeImplWithAccessChecking
> {noformat}
