[8u] RFR: 8218580: endpoint identification algorithm should be case-insensitive

[Verghese, Clive]

Hi,

I am requesting review for backport of JDK-8218580

Webrev : http://cr.openjdk.java.net/~phh/8218580/webrev.8u.00/

JBS Bug : https://bugs.openjdk.java.net/browse/JDK-8218580
Original Change : http://hg.openjdk.java.net/jdk/jdk/rev/c34acb3a3330
Change Set for JDK 11 : http://hg.openjdk.java.net/jdk-updates/jdk11u-dev/rev/148957581f5c

The JBS Bug marks the issue as Introduced in 11. But checking the 8u code, it looks like the bug is effecting 8u as well.

The backport to 8u did not apply cleanly. Other than the filename changes and line number changes, one of the notable changes is that only 2 of the 3 hunks applied in ClientHandshaker.java.

The patch has passed tier-1 in Linux and no new regressions were found.

Regards,
Clive Verghese
