Did you succeed?

There are a lot of differences between the Hotspot in OpenJDK 8 and 10
and there also have been some more improvements for AppCDS in OpenJDK
11 so if you donwport it you'll probably want to downport the version
from OpenJDK 11.

That said, I think it will be a huge change and I'm not sure the
current (and future) OpenJDK 8u maintainers will want to support it.
But that's something they'll have to decide :)

I think it would be a good idea to share the patch/webrev of your
internal backport to give an idea of the required changes.
