David Smiley commented on SOLR-11334:
-------------------------------------
Thanks but the patch doesn't fix the root cause; it works around it. The root
cause is clearly {{SolrPluginUtils.split}} for producing such empty strings in
the first place. I filed a PR accomplishing the fix. I like your test!
