0N/A *
0N/A * What this testcase is to test is a (weird) coupling through the
0N/A * cached_scope_id field of java.net.Inet6Address. Native method
0N/A * NET_InetAddressToSockaddr as in Linux platform will try to write
0N/A * and read this field, therefore Inet6Address becomes 'stateful'.
0N/A * So the coupling. Certain executive order, e.g. two methods use
0N/A * the same Inet6Address instance as illustrated in this test case,
0N/A * will show side effect of such coupling.
0N/A *
0N/A * And on Windows, NET_InetAddressToSockaddr() did not assign appropriate
0N/A * sin6_scope_id value to sockaddr_in6 structure if there's no one coming
0N/A * with Inet6Address instance, which caused bind exception. This test use
0N/A * link-local address without %scope suffix, so it is also going to test
0N/A * that.
