> Resolved concurrency issue in POS tagger.
> -----------------------------------------
>
> Key: OPENNLP-1168
> URL: https://issues.apache.org/jira/browse/OPENNLP-1168
> Project: OpenNLP
> Issue Type: Improvement
> Components: POS Tagger
> Affects Versions: 1.8.4
> Reporter: Niels Schuette
> Labels: easyfix, patch
> Fix For: 1.8.4
>
>
> We encountered a concurrency issue in the pos tagger module in the class
> DefaultPOSContextGenerator.
> The issue is demonstrated in DefaultPOSContextGeneratorTest.java. The test
> "multithreading()" consistently fails on our system with the current code if
> the number of threads (NUMBER_OF_THREADS) is set to 10. If the number of
> threads is set to 1 (effectively disabling multithreading), the test
> consistently passes.
> We resolved the issue by removing a field in DefaultPOSContextGenerator.java.
