Subject RE: Running Lucene tests on a custom Directory subclass
Date Wed, 18 Dec 2013 18:48:36 GMT
Never mind... the problem was that I compiled my jar against Lucene 3.3, but tried running
against Lucene 4.4.  It works when I also run against 3.3.  (Or, at least, I get test failures
that make sense!)
