WSO2 ESB 4.8.1 ОШИБКА Между publicId и systemId требуются пробелы.

Мы работаем с WSO2 ESB 4.8.1 с JAVA 1.7.0_55. Всегда, когда мы запускаем ESB и делаем первый запрос, мы получаем эту ошибку:

После этого мы делаем тот же запрос, и все работает нормально ...

Есть предложения, чтобы избежать этой ошибки?

Анализируя ответ с этой ошибкой, мы увидели ответы с таким сообщением:

"Error Code: 502 Proxy Error. The ISA Server denied the specified Uniform Resource Locator (URL).

После отладки исходного кода ESB мы увидели в классе synapse-nhttp-transport была ошибка, при которой, хотя значения файла /repository/conf/axis2/axis2.xml, содержащиеся в nonProxyHosts, всегда отправляются через прокси.

Прокси-сервер был тем, кто сократил трафик, и возникшая ошибка была вызвана ответом от него.

Чтобы исправить создал патч, изменяющий класс, оставляя его следующим образом:

public HttpHost selectProxy(final HttpHost target) {
  if (this.proxy != null) {
    if (knownProxyHosts.contains(target.getHostName().toLowerCase(Locale.US))) {
      return this.proxy;
    } else if (knownProxyHosts.contains(target,getHostName().toLowerCase(Locale.US))) {
      return null;
    } else {
      // we are encountering this host for the first time
      if (!isByPass(target.getHostName().toLowerCase(Locale.US))) {
        return this.proxy;
      } else {
        return null;
      }   
    }
  }
  return this.proxy;
}

Кроме того, WSO2 получил уведомление об исправлении этой ошибки.
