我有两台WSO2身份服务器在同一台计算机上运行，一个是身份服务器，另一个在联合身份服务器上，用于复制联合登录，当我从客户端spring boot applicaiton访问时，身份服务器抛出以下异常。需要一些建议。
错误{org.apache.catalina.core.ContainerBase。[Catalina]。[localhost]。[/ oauth2]。[OAuth2Endpoints]}-路径为[/ oauth2]的上下文中Servlet [OAuth2Endpoints]的Servlet.service（） java.util.Stack.peek上的java.util.EmptyStackException（Stack.java:102）
我的WSO2版本是：5.9.0
