Occasionally I am getting a NullPointerException in DependencyUtility.java.
Seems to stem from this line where the possibility of a null Head value looks
to the be cause - "if (id1==id2 ||
anodes.get(id1).getId()!=anodes.get(id2).getHead().getId()) {"
Here's the full error message -
org.apache.uima.analysis_engine.impl.AggregateAnalysisEngine_impl
processAndOutputNewCASes(275)
SEVERE: Exception occurred
org.apache.uima.analysis_engine.AnalysisEngineProcessException: Annotator
processing failed.
