Run a regression test closed/java/awt/event/MouseWheelEvent/WheelScrollEnabled/WheelScrollEnabled, and you'll find that mouse wheel scrolling enabled when it should be disabled and vice versa. Apparently a native method under setWheelScrollingEnabled() does receive a wrong boolean parameter.
LWScrollPanePeer doesn't respect wheelScrollingEnabled property
and doesn't implement several methods that are necessary
to support scrolling with the mouse wheel.
