Hi there, I'm wondering if someone would be able to review https://github.com/openjdk/jdk21u-dev/pull/1020 for me. There were a couple small merge conflicts.
I did try to cc this list from the PR, but that didn't seem to work for me. ---- I am backporting this fix because I am being affected by [JDK-8335181]( https://bugs.openjdk.org/browse/JDK-8335181). I had to downgrade to HTTP/1.1 in order to use `HttpClient`. I needed to resolve two minor conflicts in `MultiExchange.java` due to [JDK-8191494](https://bugs.openjdk.org/browse/JDK-8191494) being applied slightly differently in different projects. In both cases, I kept the change closer to upstream. The conflicts were: * Explicit vs implicit null field initialization * Different debug log message ### Tests All tests in the GitHub actions have passed. I have run the `jdk/java/net` tests locally and there were several failures, including 4 within `java/net/httpclient`. However, I have confirmed that all the failed tests also fail before applying the patch, so they seem to be unrelated. Here is a full list of the failures: * java/net/DatagramSocket/B6411513.java: java.net.DatagramSocket.receive: packet isn't received * java/net/DatagramSocket/SendReceiveMaxSize.java: This test verifies that on macOS, the send buffer size is configured by default so that none of our implementations of the UDP protocol will fail with a "packet too large" exception when trying to send a packet of the maximum possible size allowed by the protocol. * java/net/httpclient/ConnectTimeoutNoProxyAsync.java: Tests for connection related timeouts * java/net/httpclient/ConnectTimeoutNoProxySync.java: Tests for connection related timeouts * java/net/httpclient/ConnectTimeoutWithProxyAsync.java: Tests for connection related timeouts * java/net/httpclient/ConnectTimeoutWithProxySync.java: Tests for connection related timeouts UPDATE: I've run the rest of the tier2 tests and there were two additional JDK failures that appear to be unrelated: * com/sun/jndi/dns/ConfigTests/Timeout.java: Tests that we can set the initial UDP timeout interval and the number of retries. * com/sun/jndi/ldap/LdapPoolTimeoutTest.java: Multi-threaded client timeout tests for ldap pool -- Ryan
