I think you may use a different JRE version, which has different methods in HttpStatusCode. @CzyerChen do you know this?

[klllmxx]

I can only find 2.23 support here. https://github.com/apache/skywalking-java/blob/main/test/plugin/scenarios/gateway-2.1.x-scenario/support-version.list#L18

And demo project is in https://github.com/apache/skywalking-java/tree/main/test/plugin/scenarios/gateway-2.1.x-scenario

Can running the business on any JDK, such as 8 to 17, and using the corresponding Spring Cloud Gateway version and probe, make the business normal and successfully detected

[wu-sheng]

This is a CI plugin test. We use that to verify the plugin works. We never guaranteed it always works. Plugins are from global contributors.

I don't know what you mean by all the above words. It doesn't look like a question but an unrealistic expectation.

[wu-sheng]

I provided what we have. If you want to fix it, you need to debug the code and understand it. We would not debug for you.

Yes I konw,for now belong to my problems,What I need to do now is to adjust the Spring Cloud Gateway version to be compatible with it without affecting the normal business traffic access of the gateway module~

Thank you , you are best man~
