Expose a testConnection operation via JMX

Hi,

would it be possible to expose a "tesConnection" method to JMX and/or the profile service, that basically tries to get a connection with the backend database and returns true if this was successful. The connection itself could directly be closed or put back into the pool. Obtaining the connection should always try to really hit the database and not just get a connection from the pool (unless the valid connection checking mechanism is used, which may or may not be configured on a datasource).

Such an operation could be very handy for tools like Jopr.
