-------------------------------------

bq. I thought we were in agreement that they shouldn't be in the shaded jar. 
Why would we publish them to downstream? They're used in a test we run 
internally, we don't intend for them to be used downstream, right?
Ideally, it is true that these test jars are not marked as public or 
LimitedPrivate so shouldn't be used by downstream projects. However, it would 
be great if we can check those main stream projects, such as HBase, Hive, etc. 
won't use them at all. Otherwise, some related tests for downstream projects 
could get break. I like the idea to separate it into a dedicated JIRA for 
additional discussion and verification. [~busbey], what do you think?

Xerces sounds like a complicated issue across different JVMs. Can we just leave 
it there or treat it as normal third party classes? Any side-effect if we shade 
Xerces classes as third party classes?
