Correct. I'll rant at the colleagues. But there's no need to fix anything.

Also Correct. I fixed the bug to show openjdk8u211 now.

@aph: Can you please request ops to fix the jdk8u repo? Maybe we should at the same time also ask for an openjdk8u212 version because that's what we are working on?

Best regards
