1.5.3 Old Bug?

Further to SS's point about the Bridge...I just noticed this message related to same.

Multiple libraries were found for "Bridge.h"
Used: /Users/RTMSLLC/Documents/Arduino/libraries/Bridge
Not used: /Users/RTMSLLC/Desktop/Arduino 3.app/Contents/Java/libraries/Bridge

however, I can't find the directory Contents/Java/libraries/Bridge at all on my computer and don't see how an app Arduino 3.app can have sub directories!

strange indeed
