> Review static initializers that reference subclasses
> ----------------------------------------------------
>
> Key: SOLR-16167
> URL: https://issues.apache.org/jira/browse/SOLR-16167
> Project: Solr
> Issue Type: Bug
> Affects Versions: main (10.0)
> Reporter: Michael Gibney
> Priority: Major
> Attachments: StaticInitializerReferencesSubClass.xml
>
>
> 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.
