> The AbstractComponentManager.getBundle() method may throw NullPointerException if called
after the component has been disposed off. This may cause nasty log messages in the ComponentActorThread:
> 12.02.2010 19:08:56.913 *ERROR* [SCR Component Actor] org.apache.felix.scr Unexpected
problem executing task Activate Component: org.apache.sling.engine.impl.SlingMainServlet (17)
(java.lang.NullPointerException) java.lang.NullPointerException
> 	at org.apache.felix.scr.impl.manager.AbstractComponentManager.getBundle(AbstractComponentManager.java:201)
> 	at org.apache.felix.scr.impl.ComponentActivatorTask.run(ComponentActivatorTask.java:60)
> 	at org.apache.felix.scr.impl.ComponentActorThread.run(ComponentActorThread.java:96)
> 	at java.lang.Thread.run(Unknown Source)
> The check whether a component activation task should be executed should include the possibility
that the component has been disposed off and the bundle is null.
