Subject NPE with ytex in ctakes 3.2.0
Date Fri, 10 Oct 2014 20:21:41 GMT
I'm trying to experiment the ytex in 3.2.0. Trying to run
AggregatePlaintextUMLSProcessor with the FilesInDirectoryCollectionReader
and FileWriterCASConsumer. When I try to run it against some text files it
blows up with a null pointer exception during initialization. Here's the
relevant part of the stack trace. Anyone have any ideas what I might have
wrong?:

Caused by: org.apache.uima.resource.ResourceInitializationException:
Initialization of annotator class
"org.apache.ctakes.ytex.uima.annotators.SegmentRegexAnnotator" failed.
