[7u40] Request for Phase 2 approval for 8014805: NPE is thrown during certpath validation if certificate does not have AuthorityKeyIdentifier extension

[Vincent Ryan]

Hello all,

Please approve the following fix for 7u40:

Bug: http://bugs.sun.com/view_bug.do?bug_id=8014805
Webrev: http://cr.openjdk.java.net/~vinnie/8014805/webrev.00/
Code review: http://mail.openjdk.java.net/pipermail/security-dev/2013-June/007886.html

This simple fix corrects the way an Authority Key Identifier (AKID) X.509 certificate extension is
handled during OCSP certificate validation. Two forms of AKID are permitted: hash-based and
name/serial number based. The fix for 7168191 (7u6) added a check to match AKIDs when
distinguishing certificates with the same subject name. This fix corrects that check to handle the
rare case when a certificate contains a non-hash-based AKID.

This problem does not occur in JDK 8 (because a different code path is used).

Thanks.
