I think this bug that I opened is invalid for both openjdk-9 and openjfx. Sorry for not closing it sooner.
Ubuntu has a separate package for JavaFX, currently at version 11, the Long Term Support release. The most recent release is version 15, available on September 8, 2020. OpenJFX follows the same six-month release schedule as OpenJDK, with the same version numbers, generally made available one week before each OpenJDK release. Personally, I would like to see the openjfx package updated in the same manner as the OpenJDK packages, which include the intermediate releases between the Long Term Support versions. I have been unable to find the plans for OpenJFX on Ubuntu, though. ** Changed in: openjfx (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of OpenJDK, which is subscribed to openjdk-9 in Ubuntu. https://bugs.launchpad.net/bugs/1721852 Title: JavaFX support is in Oracle JDK 9 but missing in Ubuntu OpenJDK 9 Status in openjdk-9 package in Ubuntu: Invalid Status in openjfx package in Ubuntu: Invalid Bug description: OpenJDK 9 in Ubuntu 17.10 is missing the JavaFX support found in the upstream release.
