FULL PRODUCT VERSION :
java -version
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

FULL OPERATING SYSTEM VERSION :
Windows 2000 SP2

A DESCRIPTION OF THE PROBLEM :
This technique to get rid of the stippling texture on the
cross-platform UI's toolbars no longer works in the released
version of J2SE 1.4.0 (worked fine in J2SE 1.2 and 1.3:


UIManager.put("ScrollBarUI",
"com.sun.java.swing.plaf.windows.WindowsScrollBarUI");


REGRESSION.  Last worked in version 1.3.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Use above code.
2. Watch it get a null pointer exception.


EXPECTED VERSUS ACTUAL BEHAVIOR :
The scrollbar should be the Windows style w/ no stippling.
Instead, you'll get a stack trace from a null pointer
exception.
