Oracle Java 8u161 regression in XML Schema Factory

[Bernd]

Hello,

some of our unit tests (using PowerMock and xmlunit) fail with 8u161 (and
u162) but work with 8u152.

I cant reproduce the fault in a stand-alone program so it seems to be
related to classloader/reflection magic of those tools, sorry.

Is this a regression of 8159240
<http://bugs.java.com/view_bug.do?bug_id=JDK-8159240> (not public?)

Here is the stacktrace anyway:

on the classpath jaxb-impl-2.2.5.jar but the specific packages are only
loaded from rt.jar and redefined. I asume the later is done by Powermock.

Is that something you are concerned?
