Refactored using
find . -type f -name "*.java" |\
xargs sed -i -E |\
's/\.createStanzaCollectorAndSend\((\w+)\)\.nextResultOrThrow\(\);/.sendIqRequestAndWaitForResponse(\1);/'
and some manual refactoring.
This also resulted in a refactoring of the Providers and parsing
Exceptions. NumberFormatException and ParseException can now be thrown
directly, the wrapping in a SmackParsingException is down at a higher
layer, i.e. in AbstractProvider.
The NPE is caused by an inbound presence stanza without the 'from'
attribute set. The stacktrace of the NPE is:
FATAL EXCEPTION: Smack Cached Executor

Thanks to Marcel Heckel for reporting this.
Fixes SMACK-861.
and deprecate createEntry().
createEntry() would also send a subscription request which may is
suprising given that you can also create an roster item without having
to send a subscription request out.
This also fixes a bug in
LowLevelRosterIntegrationTest.testPresenceEventListenersOffline()
where createEntry() was used, which would also trigger a presence
subscription request which in turn made the test fail if the
SubscribeListener of ensureSubscribedTo() was not yet set
up. So the test would fail depending on the timing.
Fix for SMACK-841
Since Smack 4.2.4, the getPresencesInternal method in the Roster class
can return a LruCache object, which is a LinkedHashMap with access
order. This means that any access using get or getOrDefault will be a
modification of the Map. If you loop over the keySet of the Map and
there are more than one, the second call to get will throw a
ConcurrentModificationException!
Since the keys are only used here to obtain the corresponding
values, the simplest solution is to just loop over the values instead.
Daniele Ricci reporting the following NPE using Smack 4.1.9
java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.String.indexOf(int)' on a null object reference

This is possibly caused by a service sending roster pushes for unbound
connections, i.e. where getUsers() returns 'null'. We now log such
situations instead throwing an NPE.
This adds supports for an experimental protocol flow where a pending
friend request's decission is later on deliverd to the requestor after
the owner made its decission.
