Deadlock in XMPPConnection while login and parsing stream features


The Tigase XMPP server offers in-band registration in the authenticated XML stream. This causes a deadlock in the XMPPConnection by trying to get the AccountManager while it is blocked by the login method. The bug prevent to use Smack and Spark with an Tigase server.

Actually I take this back.
I've tracked the problem and discovered that it seems tigase never sends a 'session' stream feature, only register and bind. eg:

<stream:features><register xmlns=""/><bind xmlns="urn:ietf:params:xml:ns:xmpp-bind"/></stream:features>

If I force the client to ignore the fact it never saw this feature and assume it exists then everything works.

This problem has returned
I just checked out the latest trunk (in order to try the new pubsub stuff)
and this problem exists again. I can login against tigase with my older version, but not with the latest trunk.

After a second review and long testing I committed the patch to r11227.
