Re: [osgi-dev] is AllServiceListener called with ServiceEvent of Type MODIFIED_ENDMATCH
AllServiceListener behaves identical to the ServiceListener behavior with the one exception that bundle resolution wiring does not influence which service events an AllServiceListener receives.  AllServiceListener implementations will receive the MODIFIED_ENDMATCH event.
 
It is not clear to me why we would want another interface to indicate an unfiltered listener given that current listener implementations can be registered with a null filter to be unfiltered.  It would open many questions that I think would make the API more awkward.  Would we then need an UnfilteredAllServiceListener?  What happens if such a listener is registered with a filter?  What would happen if a "normal" ServiceListener is registered with a null filter?

Subject: [EXTERNAL] [osgi-dev] is AllServiceListener called with ServiceEvent of Type MODIFIED_ENDMATCH

Hi,

1.

is AllServiceListener called with ServiceEvent of Type MODIFIED_ENDMATCH ?

I would say yes, but i am a bit curios about the explicit naming of "registered, modified, unregistering" in the javadoc. Sure , a service is modified and the MODIFIED_ENDMATCH only says something about the filter of the listener. But I could not fully convince myself. And this list needs more attention ;-)

```
JavaDoc:

 * {@code AllServiceListener} objects are called with a {@code ServiceEvent}
 * object when a service is registered, modified, or is in the process of
 * unregistering.
```


2.
is there any case where is is useful to use a UnfilteredServiceListener when registering  the listener without a filter?


Thank you and best regards
Stefan Bischof
