2 testcases ScrollbarTest0003, ScrollbarTest0004 from the
JCK1.4 test api/java_awt/interactive/ScrollbarTests.html fail.
The testcases verify the behavior of Scrollbar.setBlockIncrement(int v),
Scrollbar.setUnitIncrement(int v) methods. They fail due to the following
reason - setting negative value for increment does NOT change scrollbar
behavior. If block/unit increment is negative, the scrollbar should decrement
its value when user tryes to increment it. The specification reads
(doc/api/java/awt/Scrollbar.html):
"setUnitIncrement

public void setUnitIncrement(int v)

        Sets the unit increment for this scroll bar.

         The unit increment is the value that is added (subtracted) when
the user activates the unit increment area of the scroll bar,
generally through a mouse or keyboard gesture that the scroll bar receives
         as an adjustment event.

         Specified by:
              setUnitIncrement in interface Adjustable
         Parameters:
              v - the amount by which to increment or decrement the scroll
bar's value

setBlockIncrement

public void setBlockIncrement(int v)

         Sets the block increment for this scroll bar.

         The block increment is the value that is added (subtracted) when
the user activates the block increment area of the scroll bar,
generally through a mouse or keyboard gesture that the scroll bar receives
as an adjustment event.

         Parameters:
              v - the amount by which to increment or decrement the scroll
bar's value"

Bug is reproducible in plugin, solaris 5.8,
linux.

It seems tests failed due to native implementation of scrollbar which can't
work with negative values for block/unit increment.

Set negative value for setBlockIncrement and setUnitIncrementa attributes
After that, try to block/unit increment. The scrollbar should decrement
its value, but it increments.
