我正在使用 IBM MFP8 安全检查适配器。一旦用户通过身份验证，我的后端服务将在 JSONObject 中提供用户数据，并将该用户数据作为字符串存储在属性中。在另一个适配器中，我正在调用此用户数据并尝试再次解析为 JSONObject，并在将字符串解析为 JSONObject 时出现以下错误。请帮助确定问题所在以及如何解决此问题。

代码：

import com.ibm.json.java.JSON;
import com.ibm.json.java.JSONArray;
import com.ibm.json.java.JSONObject;

AuthenticatedUser user = securityContext.getAuthenticatedUser();            
String queryParams = (String) user.getAttributes().get("queryParams");
JSONObject queryParamsObject = (JSONObject) JSON.parse(queryParams);

错误：

    [err] org.apache.cxf.interceptor.Fault: loader constraint violation: when resolving method "com.ibm.json.java.internal.Parser.parse()Lcom/ibm/json/java/JSONObject;" the class loader (instance of com/ibm/mfp/server/core/shared/ParentLastClassLoader) of the current class, com/ibm/json/java/JSONObject, and the class loader (instance of com/ibm/ws/classloading/internal/ParentLastClassLoader) for the method's defining class, com/ibm/json/java/internal/Parser, have different Class objects for the type com/ibm/json/java/JSONObject used in the signature
