"you casted the generic TextComponent type of a chat message to a TextComponentTranslation for all messages without checking if they actually are of this type. (There should be a "ClassCastException" in the log files and in the launcher log)"

What Minecraft versions does this occur on?

Never mind, it will happen with all versions. I'll fix it for 1.7, 1.8, and 1.9 right now.
