    Description

      Platforms: ALL
      JDK: 5, 6, 7
      (this CR filed against 7)

      It is impossible to create a JTable instance when SynthLookAndFeel is installed in its initial configuration with default style factory. NullPointerException will be thrown.

      The following code will throw NPE on JDK5, JDK6b105 and JDK7:

      -------------------------------------------------------------------------------------------
      import javax.swing.*;
      import javax.swing.plaf.synth.SynthLookAndFeel;

      public class Test {
          public static void main(String[] args) throws UnsupportedLookAndFeelException {
              UIManager.setLookAndFeel(new SynthLookAndFeel());
              System.out.println("Current style factory: " + SynthLookAndFeel.getStyleFactory());
              // NPE will be thrown:
              new JTable();
          }
      }
      -------------------------------------------------------------------------------------------

      The output will be:

      Current style factory: javax.swing.plaf.synth.DefaultSynthStyleFactory@587c94
      Exception in thread "main" java.lang.NullPointerException
