Currently both Solaris and Linux Java SDK/JRE's are shipped
with Windows Look and Feel.
Steps to reproduce:
1) Run the attached testcase.
2) See the console message, It says that successfully loaded
   com.sun.java.swing.plaf.windows.WindowsLookAndFeel class.

Note: If we call UIManager.getInstalledLookAndFeels() than it don't return
Windows Look & Feel under solaris and linux, But these classes are still
bundeled in jar.

Removing Windows look and feel can reduce the jre size to some extent
as apart from UI classes for all components it includes
- Windows L&F specific icons.
- Window L&F specific resource classes.
