          Removed the "duplicates" link to JDK-8008406 since that bug has been
          closed as a duplicate of JDK-8046133 JEP 143: Improve Contended Locking
          and JDK-8046133 did not include the combined adaptive spin (bucket #1)
          or the SpinPause for SPARC (bucket #6) changes.

          The combined adaptive spin (bucket #1) or the SpinPause for SPARC (bucket #6)
          changes are not currently planned for JDK9 so changed the 'Fix Version/s' value
          to '10'.
