我正在尝试使用 Jersey 客户端访问远程 Web 服务。这是我发出请求的代码：
Client client = Client.create();
WebResource resource = client.resource(request.getUrl());
Builder builder = resource.accept("application/json");
String response = builder.post(String.class, request.getPayload());
我已将它捆绑到一个 OSGi 包中，并将其安装在 Adobe CQ CMS 上。
当尝试在 CMS 中运行请求代码时，我得到以下堆栈跟踪：

原因：com.sun.jersey.core.header.MediaTypes.(MediaTypes.java:64) 处的 javax.ws.rs.core.MediaType.valueOf(MediaType.java:119) 处的 java.lang.NullPointerException ...还有 142 个
我环顾四周，发现其他人在 MediaType 在不同平台上抛出 NullPointerExceptions 时遇到了类似的错误。
有没有人见过这个问题？
