我在执行下面的代码时遇到了问题。我也有同样的功能，执行rest方法删除和把那些是伟大的工作与相同的配置，但这不是。

public void Rest_POST(String cookie)
{
String urlString = "https://localhost:8443/rest/api/2/version";
    HttpsURLConnection urlConnection;
    String cookie = getCookie();
     String JSONString = "{" +
             "\"description\":\"An excellent version\"," +
             "\"name\":\"New Version 54164987\"," +
             "\"project\":\"zhelp\"" +
             "}";
URL url;
    OutputStream os;
    HttpsURLConnection connection = null;
    try {
        //this skips the certification check
        certificateManager.skipCertificateCheck();
        url = new URL(urlString);
        connection = (HttpsURLConnection) url.openConnection();
        connection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
        connection.setRequestProperty("Content-Language", "en-US");
        if(cookie != null) {
            System.out.println("Cookie : " + cookie.split(";", 2)[0]);
            connection.setRequestProperty("Cookie", cookie.split(";", 2)[0]);
        }

        connection.setRequestMethod("POST");
        connection.setDoOutput(true);
        connection.setRequestProperty("Accept", "application/json");
        connection.setAllowUserInteraction(true);

        os = connection.getOutputStream();
        System.out.println("JSONString : " + JSONString);
        os.write(JSONString.getBytes());
        os.flush();

        System.out.println("Connection : " + connection.getURL());
  }

这将生成错误filenotfound异常。
