Description

NIFI-4301 bumped the version of Jython from Jython 2.7.0 to 2.7.1 in order to get a fix related to the os.getpid() method. However Jython 2.7.1 does not include Xerces (which provides the SAXParser for XML parsing), so although one bug is fixed, a capability has been degraded.

Recommend explicitly adding Xerces as a dependency to the scripting NAR, and make sure the unit tests and such run for other languages, so as not to introduce a classloading issue if some engine brings their own Xerces shaded into the engine's JAR(s), for example.
