J2SE: FAIL - JDK6u4 b07
Platform[s]: FAIL - Solaris-x86, amd64, sparc, sparcv9
switch/Mode: FAIL - default

The following tests:
api/java_net/MulticastSocket/descriptions.html#setTTL
api/java_net/MulticastSocket/descriptions.html#setTimeToLive

fail on solaris platforms (verified for solaris 10 and 11) of ipv6 configured. The problem is that if solaris has ipv6 configured, for example,

ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
bge0: flags=201000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS> mtu 1500 index 2
        inet 10.16.107.33 netmask fffffe00 broadcast 10.16.107.255
lo0: flags=2002000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv6,VIRTUAL> mtu 8252 index 1

        inet6 fc00:1068::214:4fff:fe0f:d61c/64

then method NetworkInterface.isUp() throws exception while analyzing interface bge0:1:
