Socket(SocketImpl) is only specified to do a permission check when the 
impl is non-null. The socket adaptor in JDK 12 and older releases 
doesn't have a dummy impl so the change should not be needed. If there 
is a security exception thrownhere then it suggests something may be 
broken elsewhere, do you have a stack trace?
