Q: I see this warning when running my program:

WARNING: package com.sun.javafx.embed.swing.oldimpl not in javafx.swing
Waiting for debugger to connect...
Program started.

A: This is a warning related to an old package that doesn't exist in Java 14. It will only appear in debug mode and you should ignore it.
