Create a ComboBoxCellEditor with an editable combo box. Associate a validator 
with the cell editor. Enter text into the combo box which is not (yet) part of 
the items of the combo box. Within the validator's isValid-method, return an 
error message for that input. An ArrayIndexOutOfBoundsException is thrown. 
 
Reason: In the method applyEditorValueAndDeactivate() a ComboBoxCellEditor 
retrieves the selection index of the combo box, with is -1 when the entered 
text is not found in the items list of the combo box. When a validator 
determines that the input is not valid, an error message is constructed within 
that method via 
 
setErrorMessage(MessageFormat.format(getErrorMessage(), new Object[] 
{items[selection]}));  
 
which fails for selection = -1.
