Please review this trivial fix for setting "Expect" header. The original code added a new header every time. As a result, when the request was retried, it was sent with two Expect headers. The new code replaces the original Expect header instead of adding a new one.
Expect header allows only one value, "100-continue", so there's no risk of overwriting some other value. No new test. I added the bug ID to the test that was intermittently failing because of this issue. Existing tests continue to pass. Also fixed an unintentional passthrough in `switch` case that generated duplicate logs in tests. ------------- Commit messages: - Fix duplicate expect 100 Changes: https://git.openjdk.org/jdk/pull/13224/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=13224&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8262294 Stats: 8 lines in 4 files changed: 1 ins; 4 del; 3 mod Patch: https://git.openjdk.org/jdk/pull/13224.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/13224/head:pull/13224 PR: https://git.openjdk.org/jdk/pull/13224
