As someone who has tested alternative Java implementations with lucene
(e.g. Jrockit, IBM's J9, Harmony), I would only call the results very

In fact I only had one test failure, in TestIndexWriterExceptions,
which in my opinion isn't serious at all, its to test this:

I think its likely due to the way that IKVM optimizes exceptions[1],
and our unit test does wierd things with examining stacktraces and

I would suggest benchmarking!
