mattwmj opened a new issue #2768: Failed to deserialize DefaultAopProxyFactory URL: https://github.com/apache/skywalking/issues/2768 Please answer these questions before submitting your issue. - Why do you submit this issue? - [ √] Question or discussion - [ ] Bug - [ ] Requirement - [ ] Feature or performance improvement ___ ### 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? ___ ### Bug - Which version of SkyWalking, OS and JRE? 6.1.0 Linux/Windows Oracle Java8 - Which company or project? - What happen? If possible, provide a way for reproducing the error. e.g. demo application, component version. ___ ### Requirement or improvement - Please describe about your requirements or improvement suggestions.
