That's tough to tell. See Mark's comments regarding DBCP, which are
positive in my view.

Also, the C3P0 folks had another semi-release back in April, so maybe
they're actually coming back. I would highly recommend talking to the
people on that team to see what their plans are.

I can see that their forum is full of complaints about deadlock, though
that may be due to misconfiguration or their applications' interference
with the library. I wouldn't be surprised to hear a lot of complaints
about DBCP deadlocking, too.

It's like buying a wireless router on Amazon: half the reviews for X say
"best router I ever had, I switched away from Y which was a POS" and
then you go look at the reviews for Y and they say the same thing with X
and Y reversed.

I would say that if things are working for you, there's no reason to
switch at all: it's not like a connection pool is a significant part of
your infrastructure (meaning that switching shouldn't be too traumatic
to your code).
