Currently, JDK HttpClient SSE implementation incorrectly handles a
non-2xx HTTP response code for POST. Instead of immediately failing the
caller, it ignores the issue and the user awaits until the timeout kicks
in.
Set HttpClient to use HTTP/1.1 version explicitly for tests
A related problem happened with the WebClient Streamable HTTP
implementation, where the error was swallowed for non-400 responses.
