Hello Derby users,
I wanted to give a head's up on an anecdotal report of a possible
serious java 6 HP hotspot issue which can corrupt the database. I
don't have versions unfortunately, but do know the issue did not
reproduce with -Xint and that user resolved the issue by upgrading to
the latest java 6 service release on HP.
One important thing to note is that there is not currently a volunteer
in the community that runs Derby tests on HP and posts results. I would
suggest running Derby tests before deploying in production on any
untested JVM.
It would be wonderful to see a volunteer to test 10.9. The community is
testing the current release candidate.

Below is the stack trace, but of course by the time you see this, your
database is probably corrupted.

Again I apologize for the vagueness. I just thought this was worth
getting out there.
