Robert Newson commented on LUCENE-1305:
---------------------------------------


The test case indexes the Enron corpus and exercises our applications Document 
creation stuff, which is quite a few classes, most of which I can't post here. 

I'm a long term Lucene user and I've never seen this kind of failure before, so 
I'm expecting it to be an environmental issue or some ugly combination of 
pieces. I noticed that jdk6 has many hotspot bugs that affect Lucene. We've had 
to disable hotstop for invertDocument because it does, eventually, segfault. 

Our java version is;

java version "1.6.0_04"
Java(TM) SE Runtime Environment (build 1.6.0_04-b12)
Java HotSpot(TM) Client VM (build 10.0-b19, mixed mode, sharing)

> The test passes on my local machine but fails on machine in our lab. Both are 
> using JDK 6 and Ubuntu 8.04. Another interesting difference is that the 
> directory that my input files are read from is an NFS share, but the index is 
> written to a local disk. the indexing process is single-threaded. This test 
> completes successfully with lucene 2.2.0 but fails with 2.3.2 (pulled from 
> the maven2 repository).
