>> ### Description
>> `Inet6Address/B6206527.java` test creates two instances of ServerSocket, both of which are explicity bound to a Link-Local address. Neither of the ServerSocket instances are explicitly closed meaning there is no guarantee that their associated resources are freed. 
>> 
>> ### Fix
>> Each ServerSocket is instantiated in a try-with-resources block. This ensures that in both cases of success or failure within the try-with-resources block, the sockets are always closed thanks to ServerSocket implementing Closeable. The test is also now started in othervm mode as an added assurance of the test's isolation in the event that resources are not freed.
