This is a bit vague - sorry about that.
We have some objects which are used by JSPs and all
share a single database connection. When multiple
instances of the JSPs were run with the 2.0.7 driver
all was fine, but under the 2.0.11 there is amost
immediate deadlock (or at least all instances hang).
Sorry we can't give more details - feel free to remove
this report if you feel it is too vague to be of help.
