felix.http.jetty NullPointer on restart in Eclipse

Hi,

I'm currently using felix.http.jetty_3.0.3. Each time I save my code in
Eclipse, while the framework is running, it gets somehow stopped and then
restarted, I think. And on this stop and restart I always get the following
NPE:

I think it tries to remove my ServletContextListener and fails on this
somehow?

Is this a known bug? or feature? ;)

Best regards,
Thomas

Hi,

this looks like a bug :( To unregister a service, it tries to do similar
things as to register it, which then fails as the bundle is stopping.

I'll have a look

Thanks for reporting

Carsten

I just commited a potential fix, not sure if it complete fixes it though.
