That’s a good path.

Shouldn’t this be added to 11 as well? Apparently, both are affected.

The OpenJDK (except for 8 which the ELTS people and I mostly work on)
is not maintained by the debian-java people but by Doko.

The usual way to hope for inclusion is to clone the bugreport, assign
one to src:openjdk-11 and the other to src:openjdk-17, mail the patch
with a description, add the tag patch and pray.
