             Summary: [Java Broker] Java Broker leaks connections and sessions via SessionPrincipal and ConnectionPrincipal in Thread inherited access control context
                 Key: QPID-6184
                 URL: https://issues.apache.org/jira/browse/QPID-6184
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker
    Affects Versions: 0.30
            Reporter: Alex Rudyy
            Assignee: Alex Rudyy
             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.
