> If any of the java process want to enable the JMX MBean server  then following VM arguments
needs to be passed.
> {code}
> -Dcom.sun.management.jmxremote
> -Dcom.sun.management.jmxremote.port=14005
> -Dcom.sun.management.jmxremote.local.only=false
> -Dcom.sun.management.jmxremote.authenticate=false
> -Dcom.sun.management.jmxremote.ssl=false{code}
> But the issue here is this will use one more random port other than 14005 while starting
JMX. 
> This can be a problem if that random port is used for some other service.
> So support a custom JMX Server through which random port can be avoided.
