Exception in thread "Thread-3" java.lang.IllegalArgumentException: unresolvable localhost 192.168.10.66 at

It is a very known fact that Exalgic has several network interfaces (bond/eth 0,1,2, etc). The logic that Coherence uses when deciding what interface to connect to, specifically to support machines with multiple network interfaces as well as enhancements to allow the localaddress to be specified as a netmask to make configuration across larger clusters easier, makes important (even more than on previuous releases of Coherence) to make sure that the tangosol.coherence.localhost parameter is specified appropriately. From that IP address (or properly mapped host address) the desired network interface to be used can easily be found and then the Coherence cluster would work fine on it.
