[jdk21u] RFR: 8312433: HttpClient request fails due to connection being considered idle and closed

Tue Sep 5 05:45:11 UTC 2023

Backport https://bugs.openjdk.org/browse/JDK-8312433 into JDK 21u.

Not a clean backport because of minor conflict in `src/java.net.http/share/classes/jdk/internal/net/http/Http2Connection.java`, which has been resolved in this PR.
