### 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
OAP server (apache/skywalking)
### What happened
skywalking-oap:8.7.0 when i start the oap server local, it comes to an error org.apache.logging.log4j.core.config.xml.XmlConfiguration cannot be cast to org.apache.skywalking.oap.server.core.logging.log4j.OapConfiguration
it seems like the OapConfigurationFactory not working, i read the apache logging docs and the org.apache.logging.log4j.core.config.plugins.util.PluginManager source code，and i do not find PluginManager .addPackage() method is invoked in server-core/logging code
i do not quite understand the mechanisms，if i miss any setting?

Yes I agree absolutely that the default settings should be OK. That's why I ask @ayumiono to recheck and provide more information.

It is, we are using the plugin mechanism of log4j2 to implement dynamic logging configuration.
But @ayumiono you should also provide detailed steps to reproduce this (e.g. what you modified, how you run, etc.), because the settings are verified in every pull request that it works, and developers who run the OAP locally never see this error.
