REGRESSION: Wrong class returned for Tree.selectionBorderColor

XMLWordPrintable



      Name: jl125535 Date: 08/26/2003


      FULL PRODUCT VERSION :
      java version "1.4.2"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
      Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)

      FULL OS VERSION :
      Microsoft Windows XP [Version 5.1.2600]

      A DESCRIPTION OF THE PROBLEM :
      The Swing property Tree.selectionBorderColor in the Windows look-and-feel is set to an object of the wrong class (should be subclass of java.awt.Color).

      I think that part of the contract of UIDefaults is that if I ask for a property that's named '*Color' then I should get a Color (or a subclass).

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Compile the code given in the Source Code section.


      If you run it with JDK 1.3.1 you get:

      [C:/work] java -Dswing.defaultlaf=com.sun.java.swing.plaf.windows.WindowsLookAndFeel Test
      o = javax.swing.plaf.ColorUIResource[r=255,g=255,b=0]

      If you run with JDK 1.4.2 you get:

      [C:/work] C:/j2sdk1.4.2/bin/java -Dswing.defaultlaf=com.sun.java.swing.plaf.windows.WindowsLookAndFeel Test
      o = com.sun.java.swing.plaf.windows.WindowsBorders$DashedBorder@87a5cc

      Note that running "java Test" without setting swing.defaultlaf produces the expected result.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Both outputs should be the same

      ERROR MESSAGES/STACK TRACES THAT OCCUR :
      ClassCastException when casting the result to java.awt.Color

      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      import javax.swing.UIManager;

      public class Test
      {
          public static void main(String[] argv)
          {
              Object o =
                  UIManager.getLookAndFeel().
                            getDefaults().get("Tree.selectionBorderColor");
              System.err.println("o = " + o);
              System.exit(0);
          }
      }

      ---------- END SOURCE ----------

      CUSTOMER SUBMITTED WORKAROUND :
      Currently, I catch the exception and ignore the property. However, I think this may cause weird problems to other people if it happens inside of third party libraries.
