Emmanuel Hugonnet commented on ARTEMIS-2171:
--------------------------------------------
Adding Priviledged blocks around ThreadFactories is sufficient since the
AccessControlContext is captured during Thread creation.
> 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
> Priority: Major
>
> 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.
