Hello @backwaterred .
I tried to apply the patches with contributed order, but patch commands were failed.
Could you show me how to apply them ?

I suggest to apply https://github.com/openjdk/jdk11u-dev/pull/993.diff which should be equivalent to applying all the individual PRs. (They will need rebasing each time because they are not "dependent" PRs).

[TheRealMDoerr]

Btw. this one is approved and ready for integration if there are no objections.

[backwaterred]

Thanks Martin.
