Release Notes for JavaFX 24
Introduction
The following notes describe important changes and information about this release. In some cases, the descriptions provide links to additional detailed information about an issue or a change.
These release notes cover the standalone JavaFX 24 release. JavaFX 24 requires JDK 22 or later. JDK 24 is recommended.
Important Changes
JavaFX 24 Requires JDK 22 or Later
JavaFX 24 is compiled with --release 22 and thus requires JDK 22 or later in order to run. If you attempt to run with an older JDK, the Java launcher will exit with an error message indicating that the javafx.base module cannot be read.
See JDK-8340003 for more information.
JavaFX Applications Must Use --enable-native-access
Running a JavaFX application on JDK 24 will produce a warning from each of the three JavaFX modules that rely on native access, due to the changes specified in JEP 472. Each warning will include the following message:
WARNING: Restricted methods will be blocked in a future release unless native access is enabledIn order to suppress the warning now, and to be able to run your application at all in a subsequent version of the JDK, you need to explicitly enable native access for all modules that need it. This is done by passing --enable-native-access= to java on the command line, listing the modules that you grant native access. This list of modules includes javafx.graphics and, optionally, javafx.media and javafx.web, if your application uses those modules.
For example:
java --enable-native-access=javafx.graphics,javafx.media,javafx.webSee JDK-8347744 for more information.
The jdk.jsobject Module is Now Included with JavaFX
The jdk.jsobject module, which is used by JavaFX WebView applications, is now included with JavaFX, replacing the JDK module of the same name. The jdk.jsobject module is deprecated as of JDK 24, and will be removed in a future release of the JDK.
To facilitate the transition, jdk.jsobject is now an upgradable module in the JDK. This means that the version of jdk.jsobject delivered with JavaFX can be used in place of the one in the JDK to avoid the compiler warning. This can be done as follows:
Applications using the SDK
When running with the JavaFX SDK, use the --upgrade-module-path argument. For example:
javac --upgrade-module-path=/path/to/javafx-sdk-24/lib
java --upgrade-module-path=/path/to/javafx-sdk-24/libNOTE: The above will fail if you run your application with JDK 23 or earlier. JDK 24 is recommended when running JavaFX 24, but if you choose to run JavaFX 24 with an earlier JDK, use the --module-path option instead.
Applications using jlink to create a custom Java runtime image:
When creating your custom Java runtime image, put the JavaFX jmods on the module path ahead of the JDK jmods. For example:
jlink --output jdk-with-javafx \
--module-path /path/to/javafx-jmods-24:/path/to/jdk-24/jmods \
--add-modules ALL-MODULE-PATHNOTE: The above will fail if you create a custom image using JDK 23 or earlier. JDK 24 is recommended with JavaFX 24, but if you choose to run JavaFX 24 with an earlier JDK, put the JDK jmods ahead of the JavaFX jmods on the module path (that is, reverse the order of javafx-jmods-24 and jdk-24/jmods).
See JDK-8337280 for more information.
Pluggable Image Loading via javax.imageio
JavaFX 24 supports the Java Image I/O API, allowing applications to use third-party image loaders in addition to the built-in image loaders. This includes the ability to use variable-density image loaders for formats like SVG. When an image is loaded using a variable-density image loader, JavaFX rasterizes the image with the screen’s DPI scaling.
Applications that want to use this feature can use existing open-source Image I/O extension libraries, or register a custom Image I/O service provider instance with the IIORegistry class. Refer to the Java Image I/O documentation for more information.
See JDK-8306707 for more information.
ScrollPane Consumes Navigation Keys Only When It Has Direct Focus
ScrollPane now only responds to key events when it is the active focus owner. This ensures that custom controls and other UI elements work correctly inside a ScrollPane, providing a more consistent and intuitive navigation experience.
Applications that prefer the previous behavior, where ScrollPane always reacts to arrow keys and other navigational inputs, can manually restore it by adding an event handler. See this note for an example of how to do this.
See JDK-8340852 for more information.
Removed Features and Options
JavaFX No Longer Supports Running With a Security Manager
The Java Security Manager has been permanently disabled in JDK 24 via JEP 486.
Likewise, as of JavaFX 24, it is no longer possible to run JavaFX applications with a security manager enabled. This is true even if you run your application on an older JDK that still supports the security manager.
The following exception will be thrown when the JavaFX runtime is initialized with the Security Manager enabled:
UnsupportedOperationException: JavaFX does not support running with the Security ManagerSee JDK-8341090 for more information.
Known Issues
JavaFX Warning Printed for Use of Terminally Deprecated Methods in sun.misc.Unsafe
Running a JavaFX application on JDK 24 will produce a warning the first time any UI Control or complex shape is rendered:
WARNING: A terminally deprecated method in sun.misc.Unsafe has been called
...
WARNING: sun.misc.Unsafe::allocateMemory will be removed in a future releaseTo disable this warning, pass --sun-misc-unsafe-memory-access=allow to java on the command line. For example:
java --sun-misc-unsafe-memory-access=allowThis will be fixed in a subsequent version of JavaFX, after which time this flag will no longer be needed.
See JDK-8345121 for more information.
