---------------------------------------
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.
