Re-posting this question..

Isn't the "certificate_authorities" extension mandatory for TLS1.3?

The text in question says "SHOULD" and not "MUST" [1]. So while it is very desirable, I would not categorize this as a mandatory requirement.


_https://bugs.openjdk.java.net/browse/JDK-8206925_

See _https://tools.ietf.org/html/draft-ietf-tls-tls13-20#section-4.2.4_
There's a known typo in
_https://tools.ietf.org/html/draft-ietf-tls-tls13-20#section-4.4.2.2_
which from this comment:
_https://www.ietf.org/mail-archive/web/tls/current/msg23612.html_
indicates section 4.4.2.2 was a typo and "certificate_authorities" should
be used instead of "trusted_ca_keys"

Note that your links above are referencing the Internet Draft. This has been corrected in the RFC: https://tools.ietf.org/html/rfc8446#section-4.4.2.2

Should JDK-8206925 be a "bug"? Thoughts?

It seems correct as an Enhancement.
