The patch in question is in the description of 
https://bugs.openjdk.java.net/browse/JDK-8210493, correct?
I'm posting it in this thread for reference [*].

The proposed change is in the NET_InetAddressToSockaddr
function, which is used in many places. I wonder is this
change should rather be confined to PlainDatagramSocketImpl
bind ( since this is the only reported issue arising from
limiting the addition of the scope to link-local ) ?
