Comments
EVALUATION ChangingAddress.java was added as part of the changes for CR 7084030. This test fails on Windows Vista and Windows 2008. Both these Windows versions support the "new" Dual TCP/IP stack and therefore use the DualStackPlainDatagramSocketImpl implementation ( as opposed to the older TwoStacksPlainDatagramSocketImpl ). It seems that on these platforms the dual TCP/IP stack will bind the DatagramSocket to an IPv6 address even if it is connected to an IPv4 address. The test would appear to be overly restrictive.
