We're using C3P0 as our connection pool and it will consistently fail with a "No suitable driver" and never successfully reload in development mode.

Reregistering with DriverManager.registerDriver in Global.onStart does resolve the problem, though. This is probably going to cause some more issues down the road when integrating with other frameworks (such as Spring et.al), but I guess we can worry about that later. :)

Thanks!
