> --------------------------------------------------------------------------------

> 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().
