Is JavaFX Included in OpenJDK Distributions on Linux?

JavaFX in OpenJDK: Compatibility and Package Availability on Linux

JavaFX Implementation in OpenJDK

JavaFX is an integral part of the OpenJDK project and its open-source code is part of the OpenJDK repository. However, not all OpenJDK distributions include JavaFX by default, particularly OracleJDK 11 implementations and Linux package installations.

JavaFX Modules in Modern Distributions

In JavaFX 11 , JavaFX is distributed as modules or a separate SDK. Developers can include these modules on the runtime module path to use JavaFX from any modern JDK supporting the target platform. This approach ensures JavaFX availability on all supported platforms.

Addressing OpenJDK Performance Issues with JavaFX

Older discussions suggested performance concerns for JavaFX in OpenJDK, but these have since been addressed. JavaFX 11 provides efficient runtimes through platform-specific SDKs or jmods, delivered from openjfx or Maven Central.

Linux Distribution Support for OpenJFX

Currently, no known Linux distribution offers a pre-built OpenJFX package for direct installation. However, several options exist for Linux users:

• Building OpenJFX from Source: Developers can build an open JavaFX version completely from source to ensure no dependency on closed source code.

• Using a Pre-built Distribution: The Debian Linux distribution provides an OpenJFX binary distribution based on OpenJDK. Install it using:

  sudo apt-get install openjfx

  Copy after login

Legacy Differences Between OpenJDK and OracleJDK in JavaFX

Previous OpenJDK versions lacked support for some JavaFX capabilities present in OracleJDK, such as VP6 video codec and WebStart/Browser Embedded application deployment. However, these differences are now less significant in Java 9 and later versions.

For Java 8, the lack of OpenJFX packages in Linux distributions is expected to be addressed with the official release of Java 8 in March 2014. In the meantime, considering self-contained application deployment is recommended for substantial applications, effectively bundling Java and JavaFX with your application for a seamless user experience.
