[GitHub] [skywalking] SLAMDUNK7 opened a new issue, #9698: [Bug] skywalking-java can not coexist with other agents.
SLAMDUNK7 opened a new issue, #9698:
URL: https://github.com/apache/skywalking/issues/9698
### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/skywalking/issues?q=is%3Aissue) and found no similar issues.
### Apache SkyWalking Component
Java Agent (apache/skywalking-java)
### What happened
The following error occurs when I use both another JavaAgent and skywalking-java：
```
ERROR 2022-09-27 15:32:09:546 main SkyWalkingAgent : index=0, batch=[class com.google.common.eventbus.Dispatcher$LegacyAsyncDispatcher], types=[class com.google.common.eventbus.Dispatcher$LegacyAsyncDispatcher]
Caused by: java.lang.UnsupportedOperationException: class redefinition failed: attempted to change superclass or interfaces

... 12 more
```
### What you expected to happen
I expect that "class com.google.common.eventbus.Dispatcher" can be enhanced without any errors. And i expect skywalking-java can coexist with other agents.
### How to reproduce
Agent version:8.11.0
Plugin：apm-guava-eventbus-plugin
The command is like '-javaagent:xxxx-agent.jar -javaagent:skywalking-agent.jar'.
### Anything else

I am afraid we don't guarantee that. Also, as your agent is not open source, we can't know either.
You could try to put the skywalking agent as the first one.
