Eddie Epstein commented on UIMA-475:
------------------------------------
The python scenario reproduces on Windows, and may be a Python limitation.
See http://docs.python.org/api/initialization.html
"Some extensions may not work properly if their initialization routine
is called more than once; this can happen if an application calls
Py_Initialize() and Py_Finalize() more than once."

Eddie
> Document Analyzer and CPE GUI have trouble running AE's multiple times

> Key: UIMA-475
> URL: https://issues.apache.org/jira/browse/UIMA-475
> Project: UIMA
> Issue Type: Bug
> Environment: Ubuntu Linux 7.04, Java 1.5.0_11, Eclipse 3.2.2, Python
> 2.4.4
> Reporter: Andrew Borthwick
> Priority: Minor
>
> 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.
