> 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.
