Griffon / Groovy programming error : don't understand

I've rewritten this question as i've localized the problem but don't understand it ..

I'm experimenting with Griffon .. In a view class I had some code ..

new Timer(1000, { e ->
    controller.countDown()
} as ActionListener).start()

which works fine (it drives a countdown clock on the corresponding view so i'm not certain its the correct place to put it .. but it works)

I moved the code to the controller in the corresponding controllers mvcGroupInit routine and got an error .. so i changed the implementation to Java ..

Timer myTimer = new Timer(1000, new ActionListener() {
      void actionPerformed(ActionEvent e) {
            //countDown()
            println "Mmm ? "
        }
} )

and I get an error ..

2014-10-08 10:13:49,391 [main] ERROR griffon.util.GriffonExceptionHandler - Uncaught Exception

at sequencemonitor.SequenceMonitorController.mvcGroupInit(SequenceMonitorController.groovy:36)  

which points to

   Timer myTimer = new Timer(1000, new ActionListener() {
        void actionPerformed(ActionEvent e) { ....

So I copied the code into the groovy console ..

import java.awt.event.*

new Timer(1000, {e->
   println "running .." 
} as ActionListener).start()   

and ran it .. got

I dont understand why Groovy is objecting . Can someone enlighten me ?? Also is this a reasonable place to put this kind of timer given it updates a model which is reflected in the UI ..

I'm using Griffon 1.4 / Java 1.7 / .. Thanks again ..

You are getting the wrong Timer class (by default): java.util.Timer is there because everything from java.util is imported automatically in groovy. Use instead a FQN:

 new javax.swing.Timer(1000, ...
