-----------------------------
    Issue Type: Bug  (was: Improvement)

> [Broker-J] Heap memory is leaked on deletion of virtual host node
> -----------------------------------------------------------------
>
>                 Key: QPID-8156
>                 URL: https://issues.apache.org/jira/browse/QPID-8156
>             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
>            Priority: Major
>
> {{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}
