I upgraded my Openfire 4.4.4 to Openfire 4.5.0 Beta. After this my Psi chat client cannot connect to the Openfire server anymore, it was connecting fine with Openfire 4.4.4
On the server I see a client session for this Psi client which has status Detached, never seen this state before.
The error log of the server shows the following NullPointerException during processing the result of a disco#info iq:
