> This PR bumps the minimum JDK version needed to build and run JavaFX to JDK > 17, starting with JavaFX 20. > > As discussed in [this > thread](https://mail.openjdk.org/pipermail/openjfx-dev/2022-July/034874.html) > on the `openjfx-dev` mailing list, this means that we can start using > language features and APIs available from JDK 12 through 17. However, this is > not an open invitation to globally refactor data classes into records, or > change all multi-line Strings into text blocks. Rather we will be able to > start using recent JDK capabilities in new code where it makes sense to do so. > > The changes are as follows: > > 1. Added a new `jfx.jdk.target.version` property in `build.properties` to > define the minimum JDK version, and set it to 17. > 2. Bumped the minimum version of the boot JDK to 17 and the minimum version > of gradle to 7.3. > 3. Use the recent gradle feature to implement the minimum JDK version using > `--release NN` instead of `-source NN -target NN` where possible (everywhere > except when building the `javafx.swing` module and the system tests). > 4. Update `CONTRIBUTING.md` to say that JDK 17 is the minimum. > > Because this change has behavioral compatibility impact, it will need a CSR > and a release note.
