Issue/Introduction
I have a customer that is running JBoss accessing an Oracle RAC and i'm getting some strange classes showing up int he investigator under Backends related to negotiating a connection and transmission of packets. I'm just trying to get a handle on what they are telling me, if they should actually be there, etc? I'm inclined to say its' some kind of instrumentation hiccup
