> 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().
