Description Eric Williams CLA 2016-03-14 07:55:40 EDT 
On GTK when closing ControlExample, there is a NullPointerException printed in the console when closing the window:

Exception in thread "main" java.lang.NullPointerException
	at org.eclipse.swt.graphics.Device.release(Device.java:942)
	at org.eclipse.swt.widgets.Display.release(Display.java:3643)
	at org.eclipse.swt.graphics.Device.dispose(Device.java:266)
	at org.eclipse.swt.examples.controlexample.ControlExample.main(ControlExample.java:225)


Seems to be related to changes from bug 479614. Happens on both GTK2 and GTK3.
