[google-appengine] Re: XMPP Presence: getPresence and isAvailable don't work? sendPresence with PROBE is asynchronous?

'isAvailable' still does not work for me.

Anyhow, banishing of synchronous 'isAvailable' method means a pretty
big change. Previously, recipient's JID was all needed, to send a xmpp
message. From now on, GAE application have to maintain a 'roster' with
statuses of the subscribers. And now it is unable to check recipient's
status, and send a message. Status have to be already stored in
roster. And app must handle 'error' xmpp responses to adjust that
statuses. BTW, there is no methods nor classes in the current GAE Java
SDK to parse 'error' stanzas.

 Hello everyone.

 I would appreciate if somebody can clarify these things:

 1. XMPPService.getPresence(..).isAvailable() constantly returns
 'false' as of today. Is that a temporary behavior, or this methods
 don't work anymore?

 2. Is sendPresence method with PROBE PresenceType asynchronous?

 3. Is that correct, that now there is no way to check JID presence
 (whether user online) synchronously?

 I have tried to read the docs. As been noted in Version 1.5.5 release
 notes:
 ##
 In the XMPP API, getPresence() is deprecated in favor of using the
 inbound presence handlers documented 
 inhttp://code.google.com/appengine/docs/java/xmpp/overview.html#Handlin
 ##
 and getPresence marked as deprecated in the current SDK. But in Java
 world deprecated usually used to change syntax or semantics, and
 leave incorrect method to maintain legacy. But not to mark method as
 non working. So it is unclear what really happened with
 'getPresence(..).isAvailable()'.

 Thanks.

1. Still works for me AFAICS
2. Yes, it's asynchronous, the results come in at 
/_ah/xmpp/presence/available/ and /_ah/xmpp/presence/
unavailable/  however, I've found that most of the users that I probe do 
not respond with an unavailable presence, as I've mentioned here: 
https://groups.google.com/forum/#!topic/google-appengine-java/vQX4TFkY3AU
3. If XMPPService.getPresence() gets removed, then there probably will not 
be anyway to check presence synchronously except by maintaining a 
persistent list of connected JIDs, and there's plenty of issues with this 
method.

For now I'm sticking with using getPresence() as it still works for me... 
hope nothing happens to it...
