my guess is perhaps problem with apc cache on the jenkins instances or using a cached version of core.
if someone could poke at the instances, maybe that would help?

same error happened on travis with sqlite + php5.3:
https://travis-ci.org/wikimedia/mediawiki-extensions-Wikibase/jobs/51836804
though that combination passed for me here: (while strange, different failure for sqlite + hhvm)

seems that jenkins and travis are now approving again, since https://gerrit.wikimedia.org/r/#/c/192296/ was merged into core.
just a guess that php 5.3 + sqlite (+ maybe apc, with strict) had an issue with that bug and now it is fixed.

I just encountered this error during an upgrade from 1.26.4 to 1.28.0:
$ php update.php --quick Warning: require_once(includes/json/FormatJson.php): failed to open stream: No such file or directory in <path>/w/maintenance/update.php on line 29
A quick workaround was to paste this line into maintenance/update.php:
require_once '../includes/json/FormatJson.php';
and then rerun update.php.

Just ran into this after upgrading to php 7.3 on mw127 on centos.
(Oops, maybe not. The error is about FormatJson, but the source seems to be something else. It seems to be related to trying to run mw127 on php 7.3.)
