I think these are thread-safety problems related to using the same analysis engine instance?
See prototype patch on https://issues.apache.org/jira/browse/LUCENE-3731, this is also causing some performance issues I think. Currently I think because no CAS is reused, its just slow and the possibility of thread problems is low. But by reusing CAS, these tests run much faster (and of course then fail). In the prototype patch as a workaround, i added this: + // nocommit: how can we get our 'own' analysis engine from the factory? + synchronized(analysisEngine) { + analysisEngine.process(cas); + } But I don't think we should do this... we should avoid the sync here. Instead of caching in the AEFactory maybe each tokenstream should get its own AnalysisEngine so there is no sync? Otherwise, I think we need to look at something like http://uima.apache.org/d/uimaj-2.4.0/apidocs/org/apache/uima/UIMAFramework.html#produceAnalysisEngine%28org.apache.uima.resource.ResourceSpecifier,%20int,%20int%29 which can process multiple requests simultaneously, but I'm not familiar enough with the UIMA apis to know whats best here.
