> When trying a range of ports, the MBean for reporting metrics is registered
> before the connection has had an opportunity to fail. If it fails and we try
> a new port, the same MBean objectName is used for registering the new
> ThriftMetrics object created for the new server. This fails because there is
> already an MBean registered with that name. A couple possible fixes: wait to
> register until we're sure the connection has succeeded; create the timed
> processor outside the port-binding loop; or deregister the bean after a
> failure.
