Eric Pugh commented on SOLR-6934:
---------------------------------
We have the various bin/solr assert commands that could be used here, plus the
AssertTool.java has static methods that could be used.
Is this a ticket [~hossman] that we still feel is valid? If you wrote a more
specific "DO this at this point" type statement, I'd be happy to work on it.
I just need a bit more direction...

> Priority: Major

> Earlier today, sarowe backported a jetty config change that broke 5x because
> it refered to a jetty feature that only existed in jetty9 (5x still using
> jetty8).
> Ass a result, jetty started up and was listenting on the specified port - but
> the solr webapp code never loaded.
> this caused an interesting failure behavior in bin/solr...
