Hmmm, odd.  I couldn't reproduce this.  First I tried w/ the ZIP as
downloaded.  Then, I replaced the lib/lucene-core-3.0.2.jar with the
3.4.0 jar.  (Separately, I removed lucene-*-dev.jar: not sure why
those are in the zip file!).  "ant test" ran fine both times.

Did the LockTest fail or was it really during CreateTestIndex?  It
sounds like somehow something is opening a newer Lucene index than 3.x
(format -11 is likely referring to the segments file, which was added
for 3.1; so likely somehow it's using Lucene 3.0.x and trying to
access a 3.1 index).

LockTest uses an index in /tmp/index, so maybe that's where the
too-new index is being hit?
