Redmine Java api-org.json.jsonException：JSONObject文本必须以字符1处的“{”开头

Question

当我尝试运行这段代码时（问题示例摘自该web http://www.redmine.org/projects/redmine/wiki/rest api with java）：

    RedmineManager redmineManager = new RedmineManager("http://something.cz", "somekey"); //I changed these two parameters for security reasons when paste here
    System.out.println(redmineManager.getProjects().size()); //this works fine
    Issue issueToCreate = new Issue();
    issueToCreate.setSubject("This is the summary line 123");
    Issue newIssue = redmineManager.createIssue("test-project", issueToCreate); //this line throws exception

我正在使用maven（http://mvnrepository.com/artifact/com.taskadapter/redmine-java-api)，它依赖于1.23版，但是我尝试了1.12.0，也抛出了相同的异常。

我们使用的是最新的redmine 2.5.1。稳定的，但是基于stacktrace，redmine web和这个redmine api之间的通信不会发生，因为异常是在应用程序的“Parserespone”部分抛出的。

不幸的是，根据与库所有者的讨论，https://github.com/taskadapter/redmine-java-api/issues/126看起来这个问题仍然没有解决（或无法解决）

但是，GET请求工作。对于Update/Create，您可以使用纯API，如下所示。警告：禁用SSL是危险的，只能用于测试目的（比如“它能工作吗？”）
