Fixed.

Please don't spoil solutions in the comments.

Unfortunately there is an issue with the Java translation, as reported below years ago. If you know how to fix it, please go ahead and fix it in the kata, or fork the translation, or just copy-paste a fix here, since I don't know Java...

Cheers

Since the kata description says "Note: the scores will always be unique (so no duplicate values)" it seems that the author's intent was to avoid this possibility.

So probably the Issue is with random tests in your particular language - it seems you are working in Java, based on what your profile says? Someone who uses Java needs to check the random tests if so.
