The behavior of ScrollPane.setBackground() is not consistent
between Solaris and Windows.
Invoking setBackground() on a scrollpane causes the background
color of the scrollpane's scrollbars to be set on Solaris, but
not on Windows.
The attached application (ScrollpaneTest.java) sets the background
color of a scrollpane to pink, and adds a panel to the scrollpane.
The scrollpane's scrollbars are pink on Solaris, and gray on
Windows.
======================================================================

JCK awt interactive ScrollPane test failing on WinNT.

The test case states that the background should be blue and the scrollbars pink, but everything is gray on screen.
