Maybe loaded by a custom class loader over the net, e.g. from a backend (probably like an Oracle AS backend)?

Hello,

I have a very curious situation and I have been scratching my head. To investigate occassional application hangs on Tomcat 5.5 running on Solaris 10, I take Tomcat process thread dumps periodically and see many threads stuck for a long time like as follows. I looked left and right into all Tomcat jars and application war files to see if I can find the package com.evermind.server.rmi, but without any success.

I have been scratching my head as to where this is coming from.
