[7u6] request for approval, 7166570: JSSE certificate validation has started to fail for certificate chains

[Xuelei Fan]

Hi,

This is a request to backport a JDK 8 fix into JDK 7u6:
     7166570: JSSE certificate validation has started to fail for
certificate chains

The fix has already been pushed to JDK 8:
     http://hg.openjdk.java.net/jdk8/tl/jdk/rev/0f63f3390ac9

The code changes for jdk7u6 are identical to the ones in jdk8.

We need to backport the fix so that the certificate validation works as
expected. The impact of the bug is significant, some applications relies
on the validation may not work without the fix.

I intend to push it to
     ssh://hg.openjdk.java.net/jdk7u/jdk7u-dev-gate/jdk

Regards,
Xuelei
