> It appears that the first ClassLoader attached to a SessionState Static
> Instance is being reused as the parent for all future sessions. This causes
> any libraries added to the class path on the initial session to be added to
> future sessions. It also appears that further sessions may be adding jars to
> this initial ClassLoader as well leading to the class path getting more and
> more polluted. This occurring on a build including HIVE-11878. I've included
> some examples that greatly exaggerate the problem.
