When you add a server runtime through Preferences -> Server -> Runtime Environments -> Add and then in the dialog click Installed JREs to open the JREs preference window, when you then complete the runtime dialog, there is an exception thrown: {code} !ENTRY org.eclipse.jface 4 0 2014-09-16 10:25:43.559 !MESSAGE org.eclipse.swt.SWTException: Widget is disposed !STACK 0
