Apache SkyWalking Component

Java Agent (apache/skywalking-java)

What happened

Setting:

springboot 3.0.2
springcloud alibaba:2022.0.0.0
reactor-core:3.5.2
spring-cloud-starter-loadbalancer:4.0.0

When I was in the process of microservice construction, I found that if the reference in the pom.xml <spring-cloud-starter-loadbalancer.jar>; When using the debug of IDEA, the following error is reported, and the faulty package is found to be <reactor-core.jar>. This error occurs after switching between different versions,This error does not occur when running in IDEA RUN mode

#Error message:

What you expected to happen

No error message is displayed when IDEA is started using debug, and logs can be reported to the SkyWalking service successfully

How to reproduce

Create a springboot 3.0.2

Replace the pom
Use the Debug mode of IDEA to start

The agent is not for using in the IDE debug env. Choose remote debug if you need to debug agent.

One more thing, logs toolkit us compiled based on a specific logback version, it may not compatible with the one you are using in your spring.

If it is caused by the start-up mode of IDEA, but when reactor-core is not introduced, both start-up modes can be used

As that, I don't think IDE matters.

If this is caused by the introduction of reactor-core, what do I need to do to solve the problem
Thanks again for your reply

I think that is the hard part. From the logs,

attempted to change superclass or interfaces

I think it means some class we want to change/intercept has changed from a class to an interface or an abstract method. You should check which plugins are targeting reactor-core lib.

Instead of using reactor-core.jar in my code,
The error was when I integrated openFegin and found that it needed to rely on spring-cloud-starter-loadbalancer.jar;
spring-cloud-starter-loadbalancer.jar depends on reactor-core.jar, It was found that SkyWalking agent imported reactor-core.jar and this error occurred only when IDEA was started with Debug, but not when RUN was used.
To rule out other factors I did the following:

Create a new Springboot without any business code or other jar references, the pom only references reactor-core.jar and spring-boot-starter.jar

I will try to get OpenFegin to use another load balancer to see if the same problem occurs

It seems like you have something special in the classpath.
I don't know that.

It was found that SkyWalking agent imported reactor-core.jar and this error occurred only when IDEA was started with Debug, but not when RUN was used.

SkyWalking doesn't import anything new. This description is wrong.

hucowei Mar 2, 2024

Sorry, what I want to express is that when using the SkyWalking agent, this error will occur when using Maven pom.xml to introduce reactor core. jar, and this error only occurs when using Debug in IDEA, and will not occur when using RUN.

wu-sheng Mar 2, 2024

First of all, I don't know that. Meanwhile, you should not do that. The correct way to do debug for the agent, is using IDEA's remote debug. That is the only way to make sure no conflict. For the reason of that conflict, I am afraid I can't help you more.

I had the same problem with IDEA, and i found that it may be caused by IDEA debug agent，it's ok without IDEA debug mode or out of IDEA.

Thanks for helping me solve this part of the doubt.
Now I have another question: Why can I run it normally without debugging, but the log part of skywalking does not collect log information. Any suggestions?
