Code Review Request, JDK-8218580, endpoint identification algorithm should be case-insensitive

[Xuelei Fan]

Hi,

Please review this update:
    http://cr.openjdk.java.net/~xuelei/8218580/webrev.00/

Objects.equals is case-sensitive, and should not be used to recognize 
case-insensitive objects.

Trivial update, no new regression test.

Thanks,
Xuelei
