Greg Bowyer commented on PYLUCENE-11:
-------------------------------------
It might be numeric terms in the index, (it might be my environment)
I will try to get a small test index built
-XX:+UseCompressedOops is not a lucene corrupting flag, it is to reduce
the overhead of a small (say < 4G) heap on a 64bit machine, that is it
makes java Ordinary Object Pointers not the full native word size for
the machine, saving space in the heap.
We have been running -XX:+UseCompressedOops for a long time in
production with no ill effects (there its Solr/Lucene not pylucene)

------------------------------------
With an index of mine, I cannot reproduce this bug.
Could you please attach a small index that reproduces this ?
(or send me a link where I could download a not so small index from ?
What is this flag: -XX:+UseCompressedOops ?
I seem to remember reading somewhere that there are crashes in Lucene with these flags in early Java 1.7 releases (I could be wrong about this particular flag).
Does your script still crash without that flag ?
