Set:

~        removeAbandonedTimeout="30"
~        logAbandoned="true"

on your <Resource> and you'll get stack traces in your log files when
connections are held for more than (in this case) 30 seconds. All of my
queries are nearly instantaneous, so a 30-second connection checkout is
considered a leak.

Wow, that's odd. Which logging mechanism are you using? Is the clock on
your server correct?

In my experience, the JAR either works or it doesn't. We had someone
check a JAR file into CVS without setting the "kb" flag (sets it to
binary) and everyone who was using win32 started getting errors all over
the place.
