Head's up for HP corruption issue

[Katherine Marsden <km...@sbcglobal.net>]

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.
