Best Practices for managing JavaFX Screens

I tried a few approaches for managing "screens" from fxml centrally, but none was satisfactory to me. I tried implementing a dynamic registry, but searching through the classpath was too complicated for me. I tried having a public static method to load the scene, but that meant a lot of duplicated code for loading fxml and needlessly implemented methods that all do the same. My internal code quality metrics tell me that thats not a good solution either. ...

xgettext detects false positives due to java.sql.ResultSet::getString

https://stackoverflow.com/questions/79639929/xgettext-detects-false-positives-due-to-java-sql-resultsetgetstring If I run find src -iname "*.java" | xargs xgettext -ktrc -ktr -kmarktr -ktrn:1,2 -o po/keys.pot --from-code=utf-8 to create the keys.pot file, then this contains all strings given to i18n::tr, but it also includes all strings given to java.sql.ResultSet::getString like rs.getString("Username"). How can I avoid this? I don't want to localize database columns....

Which one should I do...

I'm making a thing that allows me to grab the version of my PaperMC plugin, but I was thinking if I should make a static method for it or should I store the version in a static variable, which one is better?

    public static String getVersion() {
        return instance.getDescription().getVersion();
    }

    public static String getVersion() {
        return instance.getDescription().getVersion();
    }
