The same problem occurs in Ubuntu 18.04 with OpenJDK 10. There is only a package for OpenJFX for Java 8 but no package for Java 10
Programs like pdfsam and Cryptomator require JavaFX but I want to use Java 10. This also leads to bugs like Bug #1768565. -- 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: Confirmed Status in openjfx package in Ubuntu: Confirmed Bug description: OpenJDK 9 in Ubuntu 17.10 is missing the JavaFX support found in the upstream release.
