The `ProxyServer` does not have a `stop()` method of its own but since the `ProxyServer` is a `java.lang.Thread`, calling `stop()` on the `ProxyServer` ends up calling the `Thread.stop()`. The use of `stop()` in this test is accidental and the test should have used `ProxyServer.close()`.

Given `HttpTestServer` implements `AutoCloseable`, does a follow-up issue to change `ProxyServer` from `extends Thread implements Closeable` to `implements AutoCloseable` make sense? This can simplify several existing use sites terminating these resources, and avoid unintended `Thread` method invocations as was in this case.
