>             Project: Solr
>          Issue Type: Bug
>    Affects Versions: main (10.0)

> More general follow-up to SOLR-16165.
> There is the potential for classloading deadlock in the case where static 
> initializers reference a subclass.
> This issue could cover 1 or 2 things:
> # Fix existing issues
> # Add a build check to prevent such issues from being introduced in the future
> Fixing existing issues should be relatively straightforward, once we're 
> specifically looking for them. "in the wild" these are problematic enough 
> that it's probably worth just fixing all such issues whether or not they 
> manifest as deadlock in practice.
> It would be great if we could port/modify/leverage an existing implementation 
> that already checks for this and have it apply automatically in the build, 
> unless this approach proves impractical.
