I just backported some code to 3.6.0, and it includes tests that use org.apache.lucene.analysis.BaseTokenStreamTestCase#checkRandomData(java.util.Random, org.apache.lucene.analysis.Analyzer, int, int)
The tests that use this method fail in 3.6.0 in ways that suggest that multiple threads are hitting my token filter in ways that it's not intended to support. I've never had a failure like that with 4.1 -> 4.5. Does anyone recall if anything changed here?
