Hi Stanley, I modernized the files in LUCENE-400 a bit - you can see the details in comments I made on the issue. The results, including all files needed to address the issue, are in the file attached to the issue named "LUCENE-400.patch".
I can tell you aren't using the modernized version because I changed the file names, from NGram* to Shingle*, to avoid conflict with the pre-existing ngram* stuff. I don't know, however, whether the new patch will apply and build cleanly in the 2.2.0 code base, since it was targetted at the trunk circa version 2.3. Take a look at ShingleAnalyzerWrapperTest.java in the new patch - like you did, the tests there wrap WhitespaceAnalyser. If switching to the new code doesn't fix the issue for you, could you add a comment to the issue describing your inputs, and expected and actual outputs? Or, even better, write a unit test to cover your case.
