我正在尝试使用Jersey客户端来访问远程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());
我已将其捆绑到OSGi包中并将其安装在Adobe CQ CMS上。
尝试在CMS中运行请求代码时，我得到以下stacktrace：

引起：java.lang.NullPointerException 在javax.ws.rs.core.MediaType.valueOf（MediaType.java:119） 在com.sun.jersey.core.header.MediaTypes。（MediaTypes.java:64） ......还有142个
我环顾四周，看到其他人在不同平台上投放NullPointerExceptions的MediaType也有类似错误。
以前有人见过这个问题吗？
