Steven Hawkins commented on TEIID-601:
--------------------------------------

I can finally see what is going on here, a registry entry has been gone through a serialization/deserialization cycle through the registry cache.  That is making the binding seem remote even though it is local.  Hilarity ensues.

> I've set up a JBEDSP server on my laptop. I have been able to connect from the Console, but not really able to do much querying. This morning, I am no longer able to connect to the server (I tried SQuirreL and Console).
