      Description

      I am developing a series of Lucene tokenizers which can use UIMA for creating tokens via extracted annotations.
      While doing a stress test with lots of different strings I experienced the following:

      [junit] Testsuite: org.apache.lucene.analysis.uima.UIMATypeAwareAnalyzerTest

          [junit] The following exceptions were thrown by threads:

      I'm debugging it and see if I can come up with the exact bug (and fix)
