Bug 343389

Description Remy Suen 2011-04-20 08:13:24 EDT

1. Run the code below.
2. Resize the sash so that the tabs are obscured. Basically, drag the sash's line so it is on top of the second tab and then release the drag.
3. Now click the button on the right to dispose the second (index 1) item.
4. The program crashes with an AIOOBE.

Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new FillLayout());

SashForm form = new SashForm(shell, SWT.HORIZONTAL);

CTabFolder folder = new CTabFolder(form, SWT.NONE);
CTabItem item1 = new CTabItem(folder, SWT.NONE);
item1.setText("abc");
item1.setControl(new Composite(folder, SWT.NONE));
final CTabItem item2 = new CTabItem(folder, SWT.NONE);
item2.setText("abc");
item2.setControl(new Composite(folder, SWT.NONE));
folder.setSelection(item2);

final Button b = new Button(form, SWT.PUSH);
b.addListener(SWT.Selection, new Listener() {
  public void handleEvent(Event event) {
    item2.dispose();
  }
});
form.setWeights(new int[] { 50, 50 });

shell.setSize(300, 200);
shell.open();
while (!shell.isDisposed()) {
  if (!display.readAndDispatch())
    display.sleep();
}
display.dispose();
