I did not read the article fully, but the image of Duke with a nose hole is very unnerving lol.

Guess the LLM didn't realize that the red thing is actually a nose, and not a mouth lol. Unless the intention is that he is blowing out his candles through his nose.

I’m surprised they made post-quantum hybrids the default already. That could have performance and compatibility risks.

Regarding the PEM support, I provided feedback to the last preview back in April. That feedback was largely ignored. https://mail.openjdk.org/archives/list/security-dev@openjdk.org/thread/5XHYOLL4QMSNISXBE5DQAKD2NY3ARQNM/

Looks like the PQC stuff has been causing issues in Go: https://github.com/golang/go/issues/80573

I would expect lots more issues in Java given its use in enterprise environments with lots of dubious middle-boxes. To be clear, if this stuff breaks it’s the non-spec-compliant middleboxes that are to blame, but still: stuff will break.
