Can I please get a review of this change which proposes to fix the issue noted in https://bugs.openjdk.org/browse/JDK-8333590?
As noted in that issue the `sun.net.httpserver.UnmodifiableHeaders`, an internal class, within the `jdk.httpserver` module doesn't override the `toString()` method. `UnmodifiableHeaders` is of type `com.sun.net.httpserver.Headers` which is a public API in the `jdk.httpserver` module. When applications call `Headers.toString()`, if the instance is of type `UnmodifiableHeaders`, then the returned `String` representation shows empty headers, even when it isn't empty. The commit in this PR fixes the issue by implementing `toString()` in the `UnmodifiableHeaders` to return the correct representation of the headers. An existing jtreg test has been updated to reproduce this issue and verify the fix. ------------- Commit messages: - 8333590: UnmodifiableHeaders shadows field declared in parent class Changes: https://git.openjdk.org/jdk/pull/19555/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=19555&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8333590 Stats: 77 lines in 2 files changed: 64 ins; 1 del; 12 mod Patch: https://git.openjdk.org/jdk/pull/19555.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/19555/head:pull/19555 PR: https://git.openjdk.org/jdk/pull/19555
