[~romseygeek]: is this a side effect of some of the CoreContainer init changes
you made?
(It seems like really, REALLY, bad behavior that this stuff is somehow now
getting "lazy logged")
> core errors on startup are not showing up in the log until attempts to use
> the core?

> Key: SOLR-6265
> URL: https://issues.apache.org/jira/browse/SOLR-6265
> Project: Solr
> Issue Type: Bug
> Reporter: Hoss Man
> Priority: Blocker
> Fix For: 4.10
>
>
> As of r1612418, both the 4x and trunk svn trees seem to have a bug where any
> core specific init errors that occur on startup don't show up in the log
> until/unless someone attempts to access that core via HTTP.
> i'm not sure when exactly this bug was introduced, but it definitely isn't in
> 4.9.
> The impact on users, particularly new users, is that starting up solr with a
> mistake in your configs appears to work fine until you actually try to use
> solr and then you get ugly errors.
