Issue2478

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.

Tagging this (and others) with "gradle" on the assumption all must be considered together for 2.7.2.

It seems this went away at 2.7.1 when we stopped using/bundling the xml-apis JAR.
