SocketPermission.implies seems wrong for unresolveable hosts

Let p = new SocketPermission("invalidhost", "connect"). Then p.implies(p) is false unless -DtrustProxy=true, yet p.equals(p) is true. It seems quite strange to have
    p.equals(p) && !p.implies(p)
for any permission class. To my mind, the definition of equals for all Permission classes should be p.equals(q) iff p.implies(q) and q.implies(p).
