Stand-alone A-MQ has DBCP2, whilst OSGi version has DBCP1.4

The stand-alone version of ActiveMQ (tha unpacks from the "extras" directory in the A-MQ distribution) is supplied with DBCP2 which, so far as I know, we do not yet support. The OSGi version is supplied with the "correct" 1.4 version.

This is a minor irritation for customers, who have to remember to install the correct JAR every time they set up a broker; but an additional problem is that it muddies Red Hat's support position, which has traditionally been that we support everything we ship.
