Manual patch:

   http://cr.openjdk.java.net/~dlong/8214023/patch/

See the JDK-8214023 link for the list of changes.

The webrev is unfortunately very large, because of this change:

     [GR-12727] Fix duplicated copyright years in compiler and sdk suites.

It also corrected the copyright year for files where the year wasn't
updated after a change.
