If configured with a sufficiently big timeout, HttpClient will throw an exception when sending a request. For instance,

// var SUFFICIENTLY_BIG_DURATION = Duration.ofSeconds(Long.MAX_VALUE, 999_999_999); // (1)
// var SUFFICIENTLY_BIG_DURATION = Duration.between(Instant.now(), Instant.MAX); // (2)
        var SUFFICIENTLY_BIG_DURATION = Duration.ofMillis(Long.MAX_VALUE); // (3)
        try (var client = HttpClient.newBuilder()
                .followRedirects(HttpClient.Redirect.ALWAYS)
                .connectTimeout(SUFFICIENTLY_BIG_DURATION)
                .build()) {
            var request = HttpRequest.newBuilder(URI.create("https://dev.java"))
                    .header("Accept", "text/html")
                    .GET()
                    .build();
            var response = client.send(request, HttpResponse.BodyHandlers.ofString());
            System.out.println(response.body());
        }

Note that (2) and (3) result in a stacktrace which differs from that of (1).
