Ok, we can include it as a local fix for 8u & 11u instead, and defer
to 8u282/11.0.9 upstream, if it's going to cause an issue. I just
thought it preferable to include it upstream if possible.

Incidentally, note that this tzdata update has gone out to many
systems already and so the JDK will be behind the system tzdata
for about three months. We use the system tzdata rather than the
in-tree version in our packages, so we need this fix to make
sure the translations are in sync with that.

Any thoughts on the patch itself, so we can get it into 11u-dev? :-)

Thanks,
