Regression test test/java/awt/event/MouseWheelEvent/WheelEventTest no longer works quite right on Linux.

If the mouse cursor is over a non-scrolling Component (such as Checkbox, Button, or TextField), the mouse wheel event should be passed up to the enclosing ScrollPane and the ScrollPane should scroll. This was true in 1.4, but no longer works in 1.4.1 or 1.4.2. The scroll thumb moves, but the contents of the ScrollPane don't scroll.

This is true of RedHat 7.2 and 8.0.
