URL: https://github.com/apache/maven-mvnd/issues/681#issuecomment-1239416218
The issue seems to be caused by the logback jar leaking from the `mvnd` main
classloader to the plugin classloader. Logback defines a
`ServletContainerInitializer` which jetty tries to load and fail with the below
exception:
```
WARN] Failed startup of context
