Java ArrayStoreException使用apache httpasyncclient进行post

实际上，客户端驻留在Tomcat8080中，RESTAPI驻留在9090中。当URL移动到更高的环境时，它的URL将不同。我没有看到使用httpasyncclient调用REST API。我从Apache网站复制了代码

不确定如何使呼叫成功，即使我收到异常响应

CloseableHttpAsyncClient client = HttpAsyncClients.createDefault();
    try {
        client.start();
        JsonObject obj = new JsonObject();
        obj.addProperty("username", "username");
        obj.addProperty("password", "password");



        String serverURL = "http://localhost:9090/project/api";

        HttpPost postRequest = new HttpPost(serverURL);
        StringEntity params = new StringEntity(obj.toString(), "UTF-8");
        params.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "x-www-form-urlencoded"));
        postRequest.setEntity(params);

        Future<HttpResponse> future = client.execute(postRequest, null);
        HttpResponse response = future.get();


    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (InterruptedException e) {
        e.printStackTrace();
    } catch (ExecutionException e) {
        e.printStackTrace();
    } finally {
        try {
            client.close();
        } catch (IOException e) {
            e.printStackTrace();
        }


    }    

javadocs说

打开声明java.util.concurrent.ExecutionException异常 尝试检索已中止的任务的结果时引发 通过抛出异常。可以使用 getCause（）方法

最可能的原因-httpclient版本中的冲突。F.e.项目依赖性包括

httpclient

和

httpasyncclient

httpasyncclient

对另一版本的httpclient具有可传递的依赖关系。因此，项目依赖项有两个不兼容版本的

httpclient

。这里描述了其中一个案例，并进行了详细解释：
