[lworld] FTR, Merge status

[David Simms]

Two things happening just now:

  * mainline JDK has had shaky week with a number of failures
      o Updated *default* branch to latest tag (jdk-13+21, even if said
        tag won't appear valhalla repo tags)
  * There is a non-trivial conflict surrounding JDK-8222289
      o Merged into *lworld* from *default* up to that change only, so
        Srikanth can work his magic that issue, before we update the
        rest from default
