**Implementation note:** The feature is facilitated by `HttpConnection::label`, which should not be confused with `HttpConnection::id`. This distinction is explained in the JavaDoc of both properties. ------------- Commit messages: - Rename `HttpConnection::connectionLabel` to `label` - Revert `HttpClientImpl` changes - Replace radix-62 usage with plain numbers - Rename `HttpConnection::connectionId` to `connectionLabel` - Fix code typo in `HttpConnection::connectionLabel` - Switch to old style JavaDoc in `HttpResponse` - Add `HttpConnection::connectionId` and use that for `::connectionLabel` - Initial `HttpResponse::connectionLabel` draft Changes: https://git.openjdk.org/jdk/pull/24154/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=24154&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8350279 Stats: 557 lines in 12 files changed: 523 ins; 2 del; 32 mod Patch: https://git.openjdk.org/jdk/pull/24154.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/24154/head:pull/24154 PR: https://git.openjdk.org/jdk/pull/24154
