Yes. That's because BasicComboPopup is a JComponent, and the show()
method of JComponent is indeed deprecated.

Yes, the code you ellipsed contains a call to show(Component,int,int)
and that in turn calls setVisible, resulting in your infinite loop. The
easiest way to avoid this is to go ahead and ignore the deprecation
warning. In this case, since an interface declared an undeprecated
show() method, the warning is just being picky anyway.
