> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: 0.30
> Reporter: Alex Rudyy
> Assignee: Keith Wall
> Fix For: 0.31
>
>
> On thread creation, current caller AccessControlContext is stored in Thread
> field inheritedAccessControlContext. If such AccessControlContext contains
> references to SessionPrincipal and ConnectionPrincipal instances (i.e. thread
> is created in Connection/Session), the corresponding Session and Connection
> objects are not GC'ed until Thread stops running. If Thread is created in
> implementation of java.util.concurrent. Executor it can be re-used and remain
> alive until Executor utilizes the thread. Potentially, such threads might
> stay alive until Broker JVM is shutdown.
