Nevermind, I figured this out. I set
-Djava.util.logging.config.file=$UIMA_HOME/config/Logger.properties
and then I got a log file. The FINE messages then showed me that the
last AnalysisEngine running before the StackOverflowError was our
SentenceSegmenter module:
4/13/08 3:30:12 PM - 16:
org.apache.uima.analysis_engine.impl.PrimitiveAnalysisEngine_impl.process:
FINE: AnalysisEngine SentenceSegmenter process begin
Thanks for the help! I should be able to debug the problem from here.
