Summary: jgroups not using bind address specification

Initial Comment:
jgroups is not using the jboss bind address as its
default for its UDP ports. Running a minimal cluster
config with a bind address specified:

run.sh -c min-cluster -b 192.168.3.120

shows UDP ports 45566 and 57114 using the IN_ADDR
interface rather than the expected 192.168.3.120:

java.exe:3396   TCP     192.168.3.120:1098      0.0.0.0:0       LISTENING       
java.exe:3396   TCP     192.168.3.120:1099      0.0.0.0:0       LISTENING       
java.exe:3396   UDP     0.0.0.0:45566   *:*             
java.exe:3396   UDP     0.0.0.0:57114   *:*             
java.exe:3396   UDP     192.168.3.120:57113     *:*

Using the bind_addr attribute in the
cluster-service.xml also has no affect.

This is an artifact of the jdk1.3 MulticastSocket interface.
Only jdk 1.4 has an ability to set the bind address of the
socket. The jboss bind address is passed to the
MulticastSocket via the setInterface(InetAddress) method so
mcast traffic is sent to the desired interface even though
the socket does not appear to be bound to it.
