Hi

This is a request to backport a jdk8 fix into jdk7u60. 

8031572: jarsigner -verify exits with 0 when a jar file is not properly signed

   https://bugs.openjdk.java.net/browse/JDK-8031572

The fix is already included in jdk8 as: 

   http://hg.openjdk.java.net/jdk8/tl/jdk/rev/4d891c8db5c1

The review thread for both jdk8 and 7u was
