Well, that's pretty weird.
Can you reproduce this with a recent driver and loglevel=2 (append it as
a URL parameter to your JDBC URL) and send me the resulting debug output
offlist? It sounds like it might be hard to trigger though :(

I doubt that using DataSource will make any difference. From the stack
traces you showed, this does not look like a Java-level deadlock at all.
(I noticed that your two stack traces seem to be talking to different
server versions, though.. what's up with that?)
