<AWT Dev> [9] Review Request: 8027324 The spec for Toolkit.setDynamicLayout() and Toolkit.isDynamicLayoutActive() needs to be clarified

[Philip Race]

Hmm ... that doesn't sound like it moves us toward closure.
Yes, I see this in Toolkit.java

         // This property should never be cached
         if (propertyName.equals("awt.dynamicLayoutSupported")) {
             return 
getDefaultToolkit().lazilyLoadDesktopProperty(propertyName);
         }

So  if I put a sleep(100000) in your test after you read the property
and went and toggled this from system settings before the timer
expired your test program would not work as intended.

So we have an unfortunate name which should have been more like
"awt.isDynamicLayoutActiveOnThePlatformAtThisExactMoment"
and I need to do more reading ..
