I only briefly reviewd the code in PreparedStatement yeaterday with respect
to the usage of the SimpleDateFormat, my comments :
- Why the ThreadLocal usage, and not just syncronize on the same
SimpleDateFormat ?
- It seems to that the SimpleDateFormat is never modified after creation.
Wouldn't this mean that we actually could assign the SimpleDateFormat
object to a static member, so we only had to create the object once.
Or is concurrent usage of SimpleDateFormat.format() unsafe ?
I would prefer the latter if safe, as we would get less object creation and
synchronization.

Gunnar
