On both linux-amd64 (flicker) solaris-sparcv9 (shimmer), we are now getting the following errors in the regression suite:

TEST: java/net/MulticastSocket/SetLoopbackMode.java
TEST: java/net/MulticastSocket/TestDefaults.java
TEST: java/net/Socket/setReuseAddress/Basic.java
TEST: java/net/Socket/SetSoLinger.java
TEST: java/net/Socket/TrafficClass.java
TEST: java/net/Socket/UrgentDataTest.java
TEST: sun/security/ssl/com/sun/net/ssl/internal/ssl/SSLSocketImpl/NewSocketMethods.java

They pass just fine on the 32 bit equivalent.

There are also a bunch of new failures in the JCK, probably directly related.
