## java/net/MulticastSocket/SetLoopbackMode.java

    make test 
TEST="jtreg:test/jdk/java/net/MulticastSocket/SetLoopbackMode.java"
    
    
    STDOUT:
    IPv6 can be used
    Default network interface: null

    Test will use multicast group: /ff01:0:0:0:0:0:0:1
    NetworkInterface.getByInetAddress(grp): null
    STDERR:

    JavaTest Message: Test threw exception: java.net.NoRouteToHostException: No 
route to host: no further information
    JavaTest Message: shutting down test

    STATUS:Failed.`main' threw exception: java.net.NoRouteToHostException: No 
route to host: no further information
    
Cause looks similar to `MulticastAddresses`: virtualbox network interface:
Test: /ff01:0:0:0:0:0:0:1  ni: name:eth10 (VirtualBox Host-Only Ethernet 
Adapter)
    joinGroup(InetAddress) Failed: No route to host: no further information
Will investigate futher.
