[JAVA3D] v.1.3b1 Behavior.wakeupOn() and getWakeupCondition()?

[Fred Klingener]

I've posted a XHelloUniverse.java applet with an inner Behavior
at

http://www.brockeng.com/VMech/XBehavior/XHelloUniverse.html

 public class XBehavior extends Behavior
 {
  WakeupOnElapsedFrames alarm;
  static final boolean DEBUG = true;

  XBehavior()
  { if(DEBUG) System.out.print("XBehavior Constructor\n");
   if(DEBUG) System.out.print("  os.arch =
"+System.getProperty("os.arch")+"\n");
   if(DEBUG) System.out.print("  os.name =
"+System.getProperty("os.name")+"\n");
   if(DEBUG) System.out.print("  os.version
="+System.getProperty("os.version")+"\n");
   if(DEBUG) System.out.print("  J2 :
j2sdk-1_3_1_01a-win.exe\n");
   if(DEBUG) System.out.print("  J3D:
java3d-1_3-beta1-win-opengl-sdk.exe\n");

   alarm = new WakeupOnElapsedFrames(0);
  }

  public void initialize()
  { wakeupOn(alarm);
   if(DEBUG) System.out.print("XBehavior initialize()\n");
   if(DEBUG) System.out.print("  alarm = "+alarm+"\n");
   if(DEBUG) System.out.print("  getWakeupCondition() =
"+getWakeupCondition()+"\n");
  }

  public void processStimulus(java.util.Enumeration e)
  { wakeupOn(alarm);
   if(DEBUG) System.out.print("XBehavior processStimulus()\n");
   if(DEBUG) System.out.print("  alarm = "+alarm+"\n");
   if(DEBUG) System.out.print("  getWakeupCondition() =
"+getWakeupCondition()+"\n");
  }
 }

I patch it into the HelloUniverse just above the
objRoot.compile() in createSceneGraph() with::

  XBehavior xb = new XBehavior();
  xb.setBounds(bounds);
  objRoot.addChild(xb);

When I run it as an Applet, the console window shows:

Java(TM) Plug-in: Version 1.3.1_01
Using JRE version 1.3.1_01 Java HotSpot(TM) Client VM
. . .
XBehavior Constructor
  os.arch = x86
  os.name = Windows 2000
  os.version =5.0
  J2 :  j2sdk-1_3_1_01a-win.exe
  J3D:  java3d-1_3-beta1-win-opengl-sdk.exe
XBehavior initialize()
  alarm = javax.media.j3d.WakeupOnElapsedFrames@3bc473
  getWakeupCondition() = null

and that's all.  The model runs, but xb never wakes up.  How
come?
