>                 Key: SOLR-13959
>                 URL: https://issues.apache.org/jira/browse/SOLR-13959
>             Project: Solr
>          Issue Type: Improvement
>          Components: logging
>            Reporter: Erick Erickson
>            Priority: Major
>
> First, we still have some interesting logging bleed leaks that we can't account for, it's always possible anyway and I'm an optmist
> Second, there's a long discussion about leaked threads (albeit under Tomcat) and some vague references to rethinking how threads are handled in Log4J2. We already have a hack to not fail on leaked logger threads in our tests, perhaps this will address that need.
> Third, "Version 2.12.0 introduces support for accessing Docker container information " which may be increasingly interesting.
> I won't get to this soon, so anyone who wants to pick it up please do. Might be wise to wait until after the 8.4 branch is cut, I'm always a little leery of upgrading things just before a release.
