The ".each()" instruction doesn't work

import java.util.Date

   def Measure(Date pDate, int pPercent) {
   	mDate = pDate
   	mPercent = pPercent
   }
   Date mDate
   int mPercent
}

myMeasures = []
myMeasures << new Measure(new Date(106, 10, 9), 23)

myMeasures << new Measure(new Date(106, 10, 15), 23)
myMeasures = myMeasures.sort{a,b -> a.mDate <=> b.mDate}

myMeasures.each{laVar -> println ""+laVar.mDate+"|"+laVar.mPercent}
