Summary 0001241: Lots of InstanceAlreadyExists exceptions when using MySQL from Quercus
Description It looks like something in the current (Subversion) Quercus MySQL code isn't playing nice with JMX. I get tons of these exceptions, though the app appears to work fine. Seems to spit out one every time our code connects to MySQL, which of course happens a lot.

A slight clarification: this seems to happen every time our code connects to a particular MySQL instance for the first time (which I assume implies the creation of a connection pool for that instance). Once the site has been up for a while and we've contacted all our databases, I stop seeing the error message.
