Thanks for your report, it is fixed.

No

Hi DasBrain (and others),

good job! It's great to see that the original idea (without any non-JDK libraries) is basically still working. Or working again. :-)

Of course, this kata has always been a bit crazy, and I expected it to break whenever Codewars made some changes (for example, update to a newer JDK). Heck, I didn't even expect it to work in the first place. I expect it will break again in the future in unexpected ways. That's OK. Trying to fix it whenever it breaks would be a waste of time. Let's have fun while it lasts, and when some old solutions stop working, let's try to find new ones. But at the moment, it's definitely possible to solve this in several different ways, so I'll mark this issue as resolved.

Cheers,
Christopher

I just solved it, so solving is possible.

Looks like someone fixed it.

Yes, I think you're right about jcsahnwaldt's solution not working anymore, along with most solutions, but today, I found a solution that works.
