Backport request for https://bugs.openjdk.org/browse/JDK-8294196 to JDK 19 (and subsequently to LTS releases)

[Julian Reschke]

Hi there!

Jaikiran Pai recently fixed an HTTP/1.1 conformance issue in  HttpClient.

The fix was made last week (<https://github.com/openjdk/jdk/pull/10169>)
and the new JDK 20 EA build confirms the issue is gone.

I think it would be good if this made it into JDK 19 as well (and then
later on in LTS releases).

Cam somebody please start the process for that? (Note that I don't have
author status of openjdk).

Best regards, Julian
