Upgrade JavaFX to ver 17

The application uses JavaFX 11 which is reaching its EOL in September
2023. Thus it is better to upgrade JavaFX to the next LTS version which
is version 17.

However, after version 16, JavaFX now throws a warning when JavaFX
modules are loaded from the classpath. As there is currently no plan to
migrate to using Modules in AB3, let's include an additional log message
to inform the users to ignore the warning message.
