KeyCode returns "EQUALS" instead of "PLUS" when pressing the plus-key

Creating a key binding to the keyboard plus key does not work:

KEY_BINDINGS.add( new KeyBinding(KeyCode.PLUS, EVENT_NEXT) );

More closely examining the problem it turns out that the "+" key, being accessed by "SHIFT =" is being, returned as two separate events; one for SHIFT and one for EQUALS

this.setOnKeyPressed(new EventHandler<KeyEvent>()
{
            @Override public void handle(KeyEvent t)
            {
             System.out.println("code=" + t.getCode() + ", text=" + t.getText());
            }
        });

code=SHIFT, text=
code=EQUALS, text=+

Note that the text correctly returns "+". Something does not seem to be right there.
