Due to some changes in our requirements we need to find a connection pool provider that doesn't have a problem maintaining 20 or so pools for connections to different databases. Protomatter appears to have a deadlock bug of some kind when managing this many pools. Has anyone found dbcp incapable of managing this many connection pools in a single webapp?
