Localisation update is not doing its work properly.
Based on https://gerrit.wikimedia.org/r/#change,6094,patchset=1 which contains change https://gerrit.wikimedia.org/r/#patch,sidebyside,6094,1,languages/messages/MessagesJa.php with change details:
-'right-reupload' => '存在するファイルの上書き',
+'right-reupload' => '既存のファイルに上書き',
I'd expect http://nl.wikipedia.org/wiki/MediaWiki:Right-reupload/ja to now contain the updated translation ("+"), but it contains the old translation ("-").
Another example from a commit merged late last week:
https://gerrit.wikimedia.org/r/#patch,sidebyside,6022,1,MobileFrontend.i18n.php:
http://nl.wikipedia.org/wiki/MediaWiki:Mobile-frontend-leave-feedback-title/es
Reports on translatewiki.net indicate localisation updates have not been running properly since April 15[1], despite success messages in the server admin log[2].
