   |hi all, I have just integrated jsch into Proactive
   |(http://www-sop.inria.fr/oasis/ProActive/) and I can now
   |successfully tunnel all of the http/rmi communications of
   |proactive through ssh tunnels which is great.

It is great pleasure to hear that our stuff works for somebody.

   |I did ran into a small problem which is that the jsch library is
   |not thread-safe and I had to add a global JVM-wide lock to my
   |tunnel creation and destruction functions. Maybe it would be nice
   |to document that the library is not thread-safe (or, better make
   |it thread-safe ;-) because it took me a lot of time to debug the
   |whole system and figure out what was the cause of the intermittent
   |failures I observed.

Is it easy to reproduce that problem?

I have recognized one problem in opening and reading/writing 
simultaneously multiple channels on one ssh session.  

I had encountered that problem in integrating
jsch(Eclipse CVS-SSH2 plug-in) into Eclipse SDK 3.0.
Of course, after some efforts, that problem will not appear in 
Eclipse 3.0, but it has not be fixed yet essentially.
I have planed to try fixing that problem in this or next month. 


Thanks,
