Issue:
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

A screenshot shows two unexpected nodes 
NSProtocolStream
NetInputStream
Environment:
APM 10.5.x
Cause:
Identified backends coming from autopersist.pbd 
Resolution:
https://comm.support.ca.com/kb/entrypoints-are-still-reported-in-the-investigator-even-though-the-feature-is-disabled/kb000004902 remove lines from autopersist.pbd  Disable Automatic Entry Point Detection

Or comment out lines Found in the Autoprobe log
