### Question
- What do you want to know?
I am using SkyWalking with Spring cloud, Spring Boot, Spring OAuth2 Client and Spring Session with JDBC store.
java.io.InvalidClassException: org.springframework.aop.framework.DefaultAopProxyFactory; local class incompatible happened when more than one oauth client instance in the cloud.
I suspect that:
Spring OAuth2 Client stores DefaultOAuth2ClientContext (which contains DefaultAopProxyFactory) in session during authentication process. When SkyWalking enhance DefaultAopProxyFactory , the serializationUID is different on each service node. If node1 serialize DefaultAopProxyFactory and store it in store, when node2 try to deserialize DefaultAopProxyFactory from session store, InvalidClassException happens.
I want to know whether this is true and what I can do?
