Invoke lock callback in session thread
Injects the callback as a DroolsRunnable into the session, if there is one. Otherwise, it invokes it via the engine's thread pool. Issue-ID: POLICY-2246 Signed-off-by: Jim Hahn <jrh3@att.com> Change-Id: I214480ae675d89e7335dde4eb4abe2684f7ef8ab Signed-off-by: Jim Hahn <jrh3@att.com>
