--------------------------------------
I've reviewed the latest patch with Amrit offline today.
After which I ran precommit and tests on the latest patch. Committing this shortly.
Like SOLR-12083 If Jenkins is happy today I'll check with the RM if it's okay to backport it to the release branch. If it's too late then i'll move the CHANGES to 7.4 on master and branch7x
