Description

Null pointer exception in SRL module caused by certain ill-formed sentences (that other components handle gracefully).

Smallest workable example input:
I encouraged exercise. She needs a vaccine still but we don't have any moer now. . She will follow up with me in 4 months' time and also with her primary care physician.

</example>
The problem is something to do with the double period. Running this example in the UIMA-CVD with the AE located in "desc/analysis_engine/ClearParserSRLPlaintextAggregate.xml" produces the error.
