I wonder what's your current position about a respin of 8u272 with the
fix for JDK-8250861.

It looks like for 11u it was decided to create 11.0.9.1 with this fix
and I wonder if we shouldn't do the same for 8u272 which suffers from
the same bug. The fix for JDK-8250861 has already been pushed to the
8u-dev repository [1], but that's only for 8u282 in January?

What do the maintainers think?

Thank you and best regards,
