7u40 Request for approval for CR 8012044 - Give more information about self-suppression from Throwable.addSuppressed

[Joe Darcy]

Hello,

I'd like to backport the changes for

     8012044 - Give more information about self-suppression from 
Throwable.addSuppressed
     http://bugs.sun.com/view_bug.do?bug_id=8012044

from JDK 8 to the 7 update train. In JDK 8, the changeset is at

     http://hg.openjdk.java.net/jdk8/tl/jdk/rev/4da1d43f5843

and the patch of this changeset applies cleanly to the 7 update repo 
(other than the copyright date on Throwable).

See core-libs-dev threads about this change:
"Throwable.addSuppressed error conditions -- use the exception as the 
cause?"
