             Summary: ThreadPoolExecutor leak under SM due to lack of privileged block
                 Key: WFLY-10380
                 URL: https://issues.jboss.org/browse/WFLY-10380
             Project: WildFly
          Issue Type: Bug
            Reporter: David Lloyd
            Priority: Critical


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.
