Bug 242466 [JFace] Widget is disposed error when closing dialog from OSX dock
- run the snippet below which shows a dialog - right-click its icon in the OSX dock and select Quit -> the exception at the bottom will be spewed - it looks like the last line of Window.runEventLoop(Shell) should change from: display.update(); to... if (!display.isDisposed()) display.update(); snippet: public static void main (String [] args) { try { final Display display = new Display (); final Shell shell = new Shell (display); TitleAreaDialog dialog = new TitleAreaDialog(shell); dialog.setBlockOnOpen(true); dialog.open(); display.dispose (); } catch (Exception e) { e.printStackTrace(); } } exception: org.eclipse.swt.SWTException: Widget is disposed at org.eclipse.swt.SWT.error(SWT.java:3777) at org.eclipse.swt.SWT.error(SWT.java:3695) at org.eclipse.swt.SWT.error(SWT.java:3666) at org.eclipse.swt.widgets.Display.error(Display.java:1126) at org.eclipse.swt.widgets.Display.checkDevice(Display.java:626) at org.eclipse.swt.widgets.Display.update(Display.java:4084) at org.eclipse.jface.window.Window.runEventLoop(Window.java:832) at org.eclipse.jface.window.Window.open(Window.java:801) at win32.Main1.main(Main1.java:20)
