### Pre-check - [x] I am sure that all the content I provide is in English. ### Search before asking - [x] I had searched in the [issues](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar issues. ### Apache Dubbo Component Java SDK (apache/dubbo) ### Dubbo Version Dubbo 3.3.6, JDK 1.8 ### Steps to reproduce this issue When configuring condition route to route traffic to particular instance, there is still traffic in others ### What you expected to happen The route config should be executed exactly. When configuration is set, traffic should follow the configuration to route traffic to the specified instance. ### Anything else After debugging, the root cause is the code below in `AbstractStateRouter` ``` routeResult = doRoute(invokers, url, invocation, needToPrintMessage, nodeHolder, messageHolder); if (routeResult != invokers) { routeResult = invokers.and(routeResult); } ``` `invokers.and` should only return the invokes that contains in both lists, but the implementation of and function is adding the tailList together. Therefore ,the final routeResults are redundant. ### Do you have a (mini) reproduction demo? - [ ] Yes, I have a minimal reproduction demo to help resolve this issue more effectively! ### Are you willing to submit a pull request to fix on your own? - [x] Yes I am willing to submit a pull request on my own! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
