R Searls commented on JBWS-3778:
--------------------------------

I do not believe this is a bug but expected behavior.  Section 4.4, Default Sending 
Algorithm in RFC 1933, "Transition Mechanisms for IPv6 Hosts and Routers" explains 
the cause of the initial java.net.SocketException that is thrown.[1]  Because this
is a IPv6 ONLY network the router has no record of any IPv4 addresses, even the
multicast address,239.255.255.250 is unknown.  The router has algorithms for destination 
address lookup.  When an address can not be resolve, the router must treat it as 
"unreachable", hence the SocketException.

There is no clean solution to this issue because there is no way for an application 
to know if the network environment in which it is running is a mixed node (IPv4/IPv6) 
network and the thrown error indicates a true failure in the env or if the app is 
running in a single node type (IPv6 only nodes or UPv4 only nodes) network and the 
failure is expected.
