Installing JDK

Oracle Java Development Kit (JDK) is the only supported development kit.

For the full list of system requirements, applications, and application version levels, refer to the Unifier Tested Configurations document.

As announced in 2020, support for JavaFX on JDK 8 ended in March 2025. Starting with JDK 8 update 451, the JavaFX module, which is used by the Unifier Configurator, is no longer available as a part of the default JDK bundle distribution. Oracle continues to develop and release JavaFX as standalone modules via the OpenJFX project for the latest versions of Java only. Because the Unifier Configurator uses JavaFX, it cannot start when used with JDK 1.8 or later. This change has been addressed for environments that use JDK 11 and later to ensure that on-premises customers who use JDK 11 and later can use the Unifier Configurator.

Notes:

If you are using JDK Version 11, set the environment variable for JAVAFX_HOME.
If you install a new version of JavaFX, select Release 17; do not install Release 20 or later.
For on-premises customers that continue to use JDK 8, Oracle is providing a command-line package and instructions to work around the removal of JavaFX.
