-------------------------------------
Summary: Review static initializers that reference subclasses
Key: SOLR-16167
URL: https://issues.apache.org/jira/browse/SOLR-16167
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: main (10.0)
Reporter: Michael Gibney
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.
