Ich verwende den Apache http-Client 4.3.2, um Abrufanforderungen zu senden. Was ich getan habe ist:

private final RequestConfig requestConfig = RequestConfig.custom()
        .setConnectTimeout(1000)
        .setConnectionRequestTimeout(1000)
        .setSocketTimeout(1000)
        .build();
private final HttpClient client = HttpClientBuilder.create()
        .disableAuthCaching()
        .disableAutomaticRetries()
        .disableConnectionState()
        .disableContentCompression()
        .disableCookieManagement()
        .disableRedirectHandling()
        .setDefaultRequestConfig(requestConfig)
        .build(); 

Und beim Absenden der Anfrage:

HttpGet request = null;

try {
    request = new HttpGet(url);
    if (client.execute(request).getStatusLine().getStatusCode() == 200) {
        /* do some work here */
    }
} catch (Exception e) {
    Logger.error(e);
} finally {
    if (request != null) {
        request.releaseConnection();
    }
}

Bei einigen meiner Anfragen dauert es jedoch noch lange, bis die Zeit abgelaufen ist. Dies ist ein Stack-Trace der Ausnahme:

Gibt es einen anderen Timeout-Wert, den ich einstellen sollte? Was mache ich falsch?
