Description
When I call Connection::close(), I get an AssertionError from PacketOutputStream. Disabling assertions doesn't work because these exceptions are for some reason thrown explicitly and on purpose. Please change these to common catchable/swallowable exceptions. I am now having to catch this specifically (or worse Throwable which gets things like OutOfMemoryError) when trying to swallow exceptions on close().
Here is a stack trace with c3p0:
