As far as I could tell from what I read it is only of consequence when using Flash Player and the biggest problem caused is generating a LOT of error messages. It may even be a spurious error message generated by coding errors in Flash Player.
I am not seeing the message in any of my console logs, but all my systems are running Yosemite. It may be the case that whatever conflict was causing the error has been eliminated in more recent versions of OS X so no one is working on it any more.
