Description

Document Analyzer and UIMA CPE GUI successfully run a Python Analysis engine, but hang in the initialization step when the engine is run a second time. This happens, for instance, with the sample.py/PythonSample.xml engine distributed with the Pythonnator.

Note that if the Python Analysis engine is run directly using a CPE and run with the runCPE.sh script, I don't encounter this issue.

I get similar behavior when running the OpenNLP package from Document Analyzer, but with OpenNLP it runs twice and then runs out of memory and thrashes on the third run.
