[JDEV] Requesting a roster

[Jean-Louis Seguineau /EXC/TEC]

Emma,

The original Jabberbean 0.9 communication handling is to say a little shaky
:)
In fact if anything happen in the communication layer, it does not funnel
back the exception to the upper layer beans, and in addition the sender or
the reader java thread doesn't go away. This is why you are still in the
"connected" mode because the deconnection event has not propagated.

We faced that issue and we have modified these classes to provide a proper
multithread behaviour. The JabberBeans source package that I sent you
contains those modified classes and can just be used as a drop down
replacement.

As to why the these thread get disconnected, the original 0.9 still hold a
few XML bugs that would cause the parser to throw an exception (you know the
kind of mistake that happen when you copy a method into another class and
you change the opening tag but not the closing tag :) Again, I would suggest
you use the provided source to rebuild the library, as we went over all
those packet to check them.

Jean-Louis
