Hi, It seems that I have to use the jndi option: jnp.disableDiscovery=true to disable the multicast. I wonder how to set this option without changing the Twiddle.java code. Should I create a jndi.properties file in the twiddle.jar or should I add a parameter to my java command line in the twiddle.sh script?
