-----------------------------------
Summary: Disabling activator is managementagent triggers
NullPointerException on shutdown
Key: ACE-276
URL: https://issues.apache.org/jira/browse/ACE-276
Project: ACE
Issue Type: Bug
Affects Versions: 0.8.0
Reporter: Bram de Kruijff
The managementagent activator support disabling hardcoded activators through
system properties. When the package is "disabled" the start() is never called.
However, on destroy all activators receive a stop() regardless whether they
where started or not. In the case of a dm activator this will trigger a NPE.
Obviously we must not call stop() on activators that never received a start().
