JavaFX is needed to run audio accessors in JDK11 and later. Eclipse update needed.

[cxbrooks]

Recall that JavaFX is used by the audio accessors under CapeCode.

JavaFX was removed in JDK 11, see https://www.infoworld.com/article/3305073/removed-from-jdk-11-javafx-11-arrives-as-a-standalone-module.html

Configure, ant and the makefiles have been updated to use a newer version of JavaFX, which requires using the module system.

It is not completely clear how to update Eclipse to use the module system.

See https://openjfx.io/openjfx-docs/#install-javafx

For Java 12, we need to add:

--module-path $PTII/vendors/javafx/javafx-sdk-12.0.1/lib --add-modules javafx.controls,javafx.swing,javafx.media

to the compiler and java runtime commands in Eclipse.

Note that the javafx-sdk-12.0.1 would be different if we are using JDK11. Configure can determine the precise path.
