Sorry, I don't know how that script works (although it is in the java
client package).

OTOH I do know how the underlying MulticastMain works and I'm
wondering what difference it makes if you run it without the arguments
that the runperfest.sh script sets.

For example, you could run

./runjava.sh com.rabbitmq.examples.MulticastMain -h 192.168.1.129

To get a list of options of what you can set, pass in --help as an argument.

I don't know what " running with '  ' " means, but I don't think this
affects anything in the underlying MulticastMain class.
