/* |

|

* What this testcase is to test is a (weird) coupling through the |
|
40 |
* cached_scope_id field of java.net.Inet6Address. Native method |
|
41 |
* NET_InetAddressToSockaddr as in Linux platform will try to write |
|
42 |
* and read this field, therefore Inet6Address becomes 'stateful'. |
|
43 |
* So the coupling. Certain executive order, e.g. two methods use |
|
44 |
* the same Inet6Address instance as illustrated in this test case, |
|
45 |
* will show side effect of such coupling. |
|
46 |
* |
|
47 |
* And on Windows, NET_InetAddressToSockaddr() did not assign appropriate |
|
48 |
* sin6_scope_id value to sockaddr_in6 structure if there's no one coming |
|
49 |
* with Inet6Address instance, which caused bind exception. This test use |
|
50 |
* link-local address without %scope suffix, so it is also going to test |
|
51 |
* that. |
