LandOfSignals crash with Java >= 12 due to "Caused by: java.lang.NoSuchFieldException: modifiers"

Static fields cause this crash as Java 12 and higher no longer support overwriting final variables.

Example problematic code:

    @TagField("id")
    private final String id;

This happend with the latest version.
But I removed the final modifiers, which solved it.
Issue was on our side.
