JEP proposed to target JDK 17: 398: Deprecate the Applet API for Removal

We have no plan to ever add Applet Plugin support back into the JDK. We 
also have no plans for applet support in JavaFX WebView as a core 
feature, but even if we did add something like that (which seems 
unlikely), I can't think of a good reason why it would need (or want) to 
use the java.applet.Applet or javax.swing.JApplet classes.

Worth noting is that the Applet API will be present in JDK 17. They are 
being deprecated for removal in a future (post-17) release.
