HowTo get ResourceBundle from package?

Question

Hello, again I have rather silly question.
I'm using maven to build simple Java application packaged as jar.
I have such structure:
myapp.ui.button
-SuperButton.java
-SuperButton.png
-SuperButton.properties
-SuperButton_ru_RU.properties.
Also I have a method which loads string from ResourceBundle:
public static String readFromBundle(Class clz, String key){
        ResourceBundle resourceBundle = ResourceBundle.getBundle(clz.getName().toLowerCase()); //also tried clz.getName() and clz.getSimpleName(),
        return resourceBundle.getString(key);
    }The problem is that i get such error:
java.util.MissingResourceException: Can't find bundle for base name SuperButton, locale ru_RU
If I move SuperButton*.properties files to default package (i.e. root of the package structure), it works fine. My method locates ResourceBundle which I need and returns value by key.
But It's very bad, it the future I'll have several jars in one classpath and it's possible that different jars can have ResourceBundles with equal names. That is why I would like to keep each ResourceBundle in the package where i18n class is situated. With this approach ResourceBundles will not "cover" each other.
What do I do wrong? What do I have to do if I want to keep ResourceBundle in the same package with class? I don't wan't to keep resources in root.

The problem was in installed artifact where displayed method is situated.
problem is solved.
