Are you talking about the major java/jre repackaging issue, that was announced (proposed update procedure included) on the archlinux news-page, that you are supposed to check before an update?
If so, then you can’t really blame the distro, if you don’t follow basic best practice guidelines.
And then you’d also be pretty late to that update and should run updates more frequently. Once a week to at least once a month is a good idea. That’s the idea of a kinda bleeding edge, rolling release distro.
I used to like a bit of philosophizing, but then I had a philosophy professor who ruined all the fun. What a Kant.
