Prompt Preview

Apply the included Java 17 prompt first. JavaFX 17 requires JDK 11 or later; these rules target JavaFX 17 on Java 17, including FXML, CSS, WebView, media, desktop integration, and lifecycle, and were checked against 17.0.20.

Version, runtime, and support

  • Ship the newest JavaFX 17 CPU release and align JavaFX modules, SDK/JMOD files, native libraries, and platform classifiers with it; replacing JARs alone can leave vulnerable WebKit, media, font, or image code in the installed application.
  • Obtain matching binaries through the chosen distributor's authorized update channel and verify the support entitlement for each shipped OS and architecture. Keep JavaFX and the bundled JDK on their respective security-update schedules.
  • Plan migration around Gluon's published October 2026 JavaFX 17 LTS support boundary and confirm contractual coverage. Continue monitoring release notes and scheduled CPUs; do not assume 17.0.20 is the final JavaFX 17 release or treat a planned release as an available patch.

FXML and CSS are trusted application resources

  • Load only application-owned, integrity-protected FXML with FXMLLoader; never accept uploaded, pasted, or remotely editable FXML. Populate trusted controls through typed properties after loading instead of interpolating data into markup.
  • Review imported classes, fx:factory, fx:value, builders, setters, controllers, initialize(), and handlers as executable code. Keep any custom class loader, controller factory, builder factory, and injected namespace objects application-controlled; these hooks do not sandbox markup.
