I have ben able to extract a minimal reproducer. It is not related to
XMLUnit, only to powermock. If it instruments com.sun but not javax.xml
(and other combinations) then it fails.

For details see the readme in this maven project:

https://github.com/ecki/reproduce-schemaex

I also found a way to make it work with both versions, so its no longer an
issue for me, but there is definitely some changes (which might also be
triggered in AppServers or OSGi containers with partially reconfigured
implementations. Not sure if you want to investigate deeper).
