RelationExtractorPipeline failure

[Chase Master <ch...@gmail.com>]

Hi,

I've been running the RelationExtractorPipeline.  It works ok on some text
that includes relations, but I get a severe exception on other examples:

org.apache.uima.analysis_engine.impl.PrimitiveAnalysisEngine_impl
callAnalysisComponentProcess(407)
SEVERE: Exception

occurred
org.apache.uima.analysis_engine.AnalysisEngineProcessException: Annotator

Caused

by: java.lang.NumberFormatException: For input string: ""

I've attached the console full output.  This happens after the dictionary
lookup.

For instance, when I use "The collateral ligaments are intact although the
medial collateral ligament demonstrates mild thickening.", I get this error.

Thanks
