Michael McCandless updated LUCENE-2536:
---------------------------------------

    Attachment: LUCENE-2536.patch

Attached patch -- started from Shai's patch, tweaked it a bit, added the one line fix &
CHANGES entry.

I see the test in fact failing on 3.x.

> After several "updateDocuments" calls a rollback call does not return the index to the
prior state.
> This seems to occur if the number of updates exceeds the RAM buffer size i.e. when some
flushing of updates occurs.
> Test fails in Lucene 2.4, 2.9, 3.0.1 and 3.0.2
> JUnit to follow.
