Thanks Bela! it's indeed very annoying for occasional contributors just checking out the code and firing the testuite. In Hibernate Search we worked around it by simply avoiding need for Multicast in the stacks used for testing, but I suspect Infinispan doesn't have this luxury so it would be nice to find a way to detect and warn for this? I guess we could just abort the build with a meaningful message if you're using OSX, nobody should use it anyway :-P Sanne On 11 July 2014 15:51, Bela Ban <bban(a)redhat.com&gt; wrote: > I added some bits of advice for configuration of IP multicast routes on > Mac OS X. > > This is probably only of concern to those who want to bind to the > loopback device (127.0.0.1) and multicast locally, e.g. for running the > test suite. > > It is beyond me why a node cannot bind to 127.0.0.1 and use the default > route (0.0.0.0) for multicasting, e.g. if no multicast route has been > defined).
