Bug 331335 [Wizards] Bad implementation of IWizard's dispose() method can prevent the dialog from closing
If there is bad client code in an IWizard's dispose() method, the dialog get into a state where it cannot be closed. ------------ Run this code and try to close the wizard dialog, you will not be able to. Display display = new Display(); Wizard wizard = new Wizard() { public boolean performFinish() { return true; } public void dispose() { throw new RuntimeException(); } }; WizardDialog dialog = new WizardDialog(null, wizard); dialog.open(); display.dispose(); ------------ java.lang.RuntimeException at Main$5.dispose(Main.java:142) at org.eclipse.jface.wizard.WizardDialog.hardClose(WizardDialog.java:859) at org.eclipse.jface.wizard.WizardDialog.close(WizardDialog.java:484) at org.eclipse.jface.window.Window.handleShellCloseEvent(Window.java:741) at org.eclipse.jface.window.Window$3.shellClosed(Window.java:687) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:98)
