Right, Andreas. You have said this in the past. I will also test with your
DB. I do know Oracle recently released another patch for Java 7. I do NOT
know if this has any impact on the situation here.  And, because "jdbc"
tuning can be a bit touchy at times, it's still difficult, without knowing
specific individual setups, what is going on. I hope you provided many
details in whatever issue you filed on this. I would love to test with a
mySQL DB. I may resort to this at some point.
