> A user created context classloader in the current patch does not have the system context
as it parent.  If the system context contained Accumulo jars, then the user context would
have to add its own Accumulo jars.  The drawback of this is that the user context may use
a different version of accumulo jars than the system context leading to unexpected behavior.
  The advantage of this is that user context could load newer jars.  For example, if Accumulo
depended on an old json library the user context could load a newer version with no problems.
