In Hibernate Search we worked around the multicast problem by dropping the need for multicasts: essentially all our tests are now using SHARED_LOOPBACK and SHARED_LOOPBACK_PING. But before that decision, Hardy had made the following interesting solution for our Maven build. Having agreed that this is not a JGroups bug but rather a weird configuration on apple machines, we'd expect apple users to have to fix their routing table; this would need some appropriate instructions in the usual places, but the patch below also provides for a user friendly error message to those who might not have set it up: https://github.com/hferentschik/hibernate-search/commit/d207ba088f8bec5d0... We choose for the simplicity of the in-JVM loopback tests as we build on top of Infinispan, and trust you guys to deal with the network complexities, but I think Hardy's solution might be a good fit to be applied to Infinispan?
