>            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}
