[7u-dev]Request for approval 8014618, Need to strip leading zeros in TlsPremasterSecret of DHKeyAgreement

[Xuelei Fan]

Hi,

This is a request to backport a JDK 8 fix into JDK 7u-dev:
    8014618: Need to strip leading zeros in TlsPremasterSecret of
DHKeyAgreement

The fix has already integrated into JDK 8:
    http://hg.openjdk.java.net/jdk8/tl/jdk/rev/6407106f1b1c

The code changes for jdk7u are identical to the ones in jdk8.

The fix addresses a regression issue of JDK-7146728.  We need to address
the issue in JDK 7 as it impact the usability of JSSE in JDK 7.


Thanks,
Xuelei
