[esb-java-user] How to operate ESB and WSAS on the same machine.

The NIO code has a slight probability to behave differently with clients 
on the same physical host and others - and this depends mainly on the 
OS. (e.g. I first saw this couple of years ago with a very old Sun 
Solaris). I do not want to comment on this specific issue without 
further analysis, but like Ruwan said, quite a few issues have been 
fixed on the trunk after the Synapse 1.2/ESB 1.7.x releases, with help 
mainly from real users who use it in production
