I can reproduce this issue. This is not a bug, the snippet is calling display.getActiveShell before shell is active, so it will always be null. Changing it to something like
shell.addMouseMoveListener(e -> {
System.out.println(display.getActiveShell() == shell);
});
gives the correct result.

To reproduce this error here is the snippet: import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell; public class ShellTest { public static void main (String [] args) { Display display = new Display(); Shell shell = new Shell(display); shell.open(); System.out.println(display.getActiveShell() == shell); while (!shell.isDisposed ()) { if (!display.readAndDispatch ()) display.sleep (); } display.dispose (); } }
