hotspot messages about the future?

[Kelly O'Hair]

When did the  hotspot -XX options start spitting out messages like this?


svc6<1263> java -XX:+CMSClassUnloadingEnabled -XX: 
+CMSPermGenSweepingEnabled -version
Please use CMSClassUnloadingEnabled in place of  
CMSPermGenSweepingEnabled in the future
java version "1.6.0_10"
Java(TM) SE Runtime Environment (build 1.6.0_10-b33)
Java HotSpot(TM) Server VM (build 11.0-b15, mixed mode)


I always thought silence was golden?
