The previous site where the callback was invoked was only reached if
there was also a user status on the unvailable presence. But those are
not part of unavilable presences upon room destruction.
Fixes SMACK-888.
There is no need to duplicate that code. Also ensure that
userHasLeft() is invoked *before* the listeners are invoked, so that
e.g. isJoined() returns false in the listeners.
Use EntityBareJid just as its done within PepManager. There is no need
for AsyncButOrdered in the PEP user managers, as PepManager already
takes care of that. Also the message carrying the PEP event should
always be the last parameter of the callbacks, as it is the least
important piece of information.
This also removes the powermock dependency. Although powermock is a
fine library, it currently prevents dropping Junit4. And since we only
use the Whitebox API of powermock, this simply replaced powermock's
Whitebox with our own.
This mini assignment kicked-off with replacing `pubsub` with `pep`,
but later transformed into something more.
The alterations and additions in this commit:
a) GeoLocation.
1) Add Documentation.
2) Add `EMPTY_GEO_LOCATION` to be used while
`stopPublishingGeoLocation()` is called.
b) Add GeoLocation IntegrationTest.
c) Add GeoLocation Listener.
d) GeoLocationManager.
1) Add Documentation.
2) Replace `pubsub` with `pep`.
3) Add methods to add-and-remove GeoLocationListeners.
4) Enable GeoLocation by default.
e) Add `package.info` for GeoLocation Integration Test.
Returning a generic would allow for
List<ExtensionElement> list = stanza.getExtension("foo", "bar");
to compile (Note the we are calling getExtension(), not
getExtension*s*()).
Users are encouraged to use the type safe getExtension(Class<? extends
ExtensionElement) variant instead.
Fixes SMACK-825.
Those, relatively new, listeners guarantee that the individual
listeners are not invoked in concurrently while preserving the
order. Exactly what MultiUserChat previously did with AsyncButOrdered,
which is now no longer needed and hence can be removed.
