Take the "TaskSample" Sample code from the Ensemble..

comment out this line below to show a Interderminate Progress Indicator

p.progressProperty().bind(task.progressProperty());

So what should be expected is a spinning progress indicator to be displayed.

In the later builds of JDK 8, b106 & b108 the progress indicator is static and not spinning.
