Pei Chen commented on CTAKES-184:
---------------------------------
Thanks for catching that Tim.
This edge case (single word sentence) always seems to bite us in the rear end.
If you have chance, could you commit a test data file that contains a single
token sentence somewhere so that it could be used in the unit tests and
regression-test? If not, I'll try to add it in as soon as I get a chance over
the next few weeks.

> sometimes return the head node, which will not have certain pieces of
