I have checked the workflow results, and I find that many other modules fail but I think I don't change them. For my dubbo-samples-stub module, I run its integration test locally with 3.2.0-beta.4 successfully. But if run with 3.2.0-beta.5, the below error will appear. java.lang.IllegalStateException: Extension instance (name: observationreceiver, class: interface org.apache.dubbo.rpc.Filter) couldn't be instantiated: null
