EVALUATION I ran the jtreg and JCK tests for DatagramChannel on 10.6.8 and only observed two regression tests failing: java/nio/channels/DatagramChannel/SelectWhenRefused.java - covered by 7132679. java/nio/channels/DatagramChannel/MulticastSendReceiveTests.java - fails because the test attempts to join an IPv4 mutlicast group with an IPv6 - see comments.
