Please consider removing the java.xml classes from the jython-standalone-2.7 jar package and distributing them separately.  These were not present in the 2.5.4-rc1 jar.  If I understand correctly, they are present in Java-SE so should not be needed (?). 

When I upgraded from 2.5.4 to 2.7.0 other components started throwing this exception:

    Provider org.python.apache.xalan.processor.TransformerFactoryImpl not found

This issue may be related to another Python issue:  http://bugs.jython.org/issue2121

The failure is also discussed here in some detail (read way down): https://github.com/ControlSystemStudio/cs-studio/issues/110

The problem is easily reproduced.  In brief, I'm using embedding Jython in an Eclipse RCP that also uses Apache POI to read/write Excel spreadsheets.  The Poi component has to instantiate a Xalan to produce XLSX files.  When the Jython-2.7.0 jar file is present, Poi blows up with the exception shown above.  When the Jython-2.5.4-rc1 jar file is present, Poi works fine. I'll be happy to provide more detail if you need it.

Thanks for listening.

Forgot to mention: python-standalone-2.5.4-rc1 is about 10MB, 2.7.0 is about 35MB. Ouch, that's a big jump in size.

2.7.2 should be able to address this, as we move to a Gradle based build that's compatible with current Maven practice.
