Most likely the IOExceptions stem from FastCharStream of StandardAnalyzer, at least that's my experience.
See the header of your hprof file to check if that's the case.
Javacc has a gotcha in that it "likes" IOExceptions as part of the normal control flow on stream termination.
I have performance patches for this that make FastCharStream 2-10 times faster for small inputs (it
doesn't matter on large inputs), but I never bothered submitted them since they were not crucial for me,
and seeing that most submissions to lucene-dev go into a black hole anyway without any response,
neither negative or positive, simply ignored... Hint :-)
