             Summary: ThreadPoolExecutor leak under SM due to lack of privileged block
                 Key: ARTEMIS-2171
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-2171
             Project: ActiveMQ Artemis
          Issue Type: Bug
          Components: Broker
    Affects Versions: 2.6.3
            Reporter: Miroslav Novak


Description cloned from https://issues.jboss.org/browse/WFLY-10380:

Still researching the source of these leaks.

The way the leak happens is, a java.util.concurrent.ThreadPoolExecutor is constructed from an unprivileged context. The pool starts up and threads are created without a problem, however, the thread pool is never shut down. The finalizer runs but since it tries to shut down the pool with an access control context that was captured during construction, it fails because the context did not have the modifyThread RuntimePermission, and the thread pool never shuts down.

We need to identify the points where TPEs are being constructed without controlled privileges.
