I've quickly tried openjdk-11 on Ubuntu 18.10 beta: the same low-grade
font rendering. It is particularly bad in Isabelle/jEdit file-open dialog.

In the past, OpenJDK often had a much better FreeType renderer, but now
it seems to be closer to the official OpenJDK version provided by
Oracle. This (re-)unification is a good thing, but until that version
gets a proper font-renderer it is unusable.

On Windows and macOS it works all fine.
