Actually removes a bunch of code to manage the JMX connector,
since as of jdk8u102, the standard jmx connector answers to
property setting bind address -> can restrict access.
Note that the RMI connector will now (as is jdk normal)
_bind_ to 0.0.0.0, but it will not answer non-local requests
if "remote" is not enabled. This is the default jdk behaviour.
In any case, we rely on setting the appropriate properties
instead, and also allow pass-through of -D flags to java,
which in turn means those who wish can turn on both auth
and ssl, set key/trust stores etc etc.
