[OpenJDK 2D-Dev] Font rendering quality in Linux

Hi Volker, in at least one case (Android Studio openjdk 1.8.0_76-release vs
openjdk 1.8.0-internal which I compiled myself with Freetype enabled) I
compared two Openjdks, and they render fonts very differently.
I also compared Ubuntu Openjdk to apps which use Freetype for sure (e.g.
the text editor Pluma) and the rendering difference is mostly just as large.
But Oracle Jdk which, according to you, does not use Freetype, renders the
fonts just like Openjdk which must use Freetype.
Why it is like that, I don't know.
