Summary

Deprecate the FXPermission class for removal. After the removal of support for the Java Security Manager from JavaFX, this class serves no purpose. We intend to remove this class in JavaFX 26.

Problem

As of JavaFX 24, we no longer support running JavaFX applications with the Java Security Manager. Further, as of JDK 24, the Security Manager has been permanently disabled in the JDK itself and cannot be enabled. The FXPermission class no longer does anything useful and includes this API Note:

 * @apiNote
 * This permission cannot be used for controlling access to resources anymore
 * as the Security Manager is no longer supported.

Solution

Deprecate the FXPermission class for removal with the intention to remove it in JavaFX 26.
