------------------------------------------------------------
I think we need to change the existing PrincipalAccessor into an
SubjectAccessor. The TaskExecutor will merely use the returned subject from
the SubjectAccessor when elevating permissions (Subject.doAs). For the
SystemLaucher, it needs to provide a SubjectAccessor that always simply returns
the (readonly) org.apache.qpid.server.SystemLauncher#_brokerTaskSubject. For
AVH, it needs to produce a subject in the same way as today i.e. take the
calling context and add the VH principal.

> [Java Broker] Recovery of Broker preferences should happen without holding

> Key: QPID-7477
> URL: https://issues.apache.org/jira/browse/QPID-7477
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: qpid-java-6.1
> Reporter: Lorenz Quack
> Fix For: qpid-java-6.1, qpid-java-6.2
>
>
> If a {{VirtualHostLogger}} is configured it will log the recovery of Broker
> preferences on the Broker-Config thread. It should not do this.
> The cause seems to be that during execution of
> {{BrokerImpl#performActivation}} the {{Subject}} contains the
> {{VirtualHostPrincipal}}.
> I think this is related to the fact that the call stack shows that this code
> is called from the {{onSuccess}} callback of {{VirtualHostNode#doActivation}}
