Description

Looks like the xmlContent=True flag causes tika.py: Warn: Tika server returned status: 422 error

I start the tika server and then run the following code in the python kernel at bash

import tika
from tika import parser
parsed = parser.from_file('/path/to/file.rtf,'http://localhost:9003',xm
lContent=True)

I get.. tika.py: Warn: Tika server returned status: 422
Looking at the tika-server log I get the following dump:

Note: The parser seems to work fine without the xmlContent=True flag set. I get the right output but setting this flag creates the NullPointerException below
