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

A screenshot shows two unexpected nodes 
NSProtocolStream
NetInputStream

Cause

Identified backends coming from autopersist.pbd 

Environment

APM 10.5.x

Resolution
