> Summary:
> Currently there are number of options that must be configured for the JMX Console to
correctly connect, if these values are not set or correct then the connection will fail.
> However, the broker will provide the console with sufficient detail to auto-negotiate
the connection.
> QPID-1504 highlights that if we connect using the RMI connector but the server is configured
for JMXMP then we can tell.
> If we connect using JMXMP using SASL/CRAM-MD5 but the server wants SASL/PLAIN  then we
can tell as the exception is:
>     java.io.IOException: The server supported profiles [SASL/PLAIN] do not match the
client required profiles [SASL/CRAM-MD5].
> We can use this information to swap Sasl mechanism in the console and try again.
> This would mean that the end user would not have to reconfigure or have multiple start
scripts lying about so they could connect to a number of difference brokers using different
> Looking at the private class ConnectorThread in JMXServerRegistry along with the createSASLConnector
 and the constructor show that the security mechanism is hard coded but could using the above
method be derived from the broker's response and handled appropriately if the ConnectorThread
and createSASLConnector where better architected to take advantaged of the exceptions returned
from the JMXConnectorFactory.connect method
