A DESCRIPTION OF THE PROBLEM :
The documentation for the vertical and horizontal scrollbar policies states that the scrollbar policy constants are in the JScrollPane class when they are really in the ScrollPaneConstants class.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
in the setVerticalScrollBarPolicy method:
ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED
ScrollPaneConstants.VERTICAL_SCROLLBAR_NEVER
ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS

in the setHorizontalScrollBarPolicy method:
ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED
ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER
ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS

ACTUAL -
in the setVerticalScrollBarPolicy method:
JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED
JScrollPane.VERTICAL_SCROLLBAR_NEVER
JScrollPane.VERTICAL_SCROLLBAR_ALWAYS

and in the setHorizontalScrollBarPolicy method:
JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED
JScrollPane.HORIZONTAL_SCROLLBAR_NEVER
JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS
