Run the following test on Windows with 1.5.0 b48 and b49:
import java.awt.*;

class test {
    
    public static void main(String[] args) {
Frame f = new Frame("this is a test");
f.setSize(new Dimension(200,200));

f.show();
    }
}

Notice that in b48 frame has coffee-cup icon, while in b49 it doesn't have it.

Same problem reported by a CAP member:

J2SE Version (please include all output from java -version flag):
  java version "1.5.0-beta2"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta2-b50)
  Java HotSpot(TM) Client VM (build 1.5.0-beta2-b50, mixed mode, sharing)

Does this problem occur on J2SE 1.3.x or 1.4.x? Yes / No (pick one)
  No, works fine with build48

Operating System Configuration Information (be specific):
  WinXP SP1

Hardware Configuration Information (be specific):
  IBM Thinkpad T30, 512M RAM, 2GHz Intel P4m

Bug Description:
  CheckboxMenuItem does not show the "check" in the menu.

Steps to Reproduce (be specific):
  Compile and run the following class. Item #2 in the menu is a
  CheckboxMenuItem. By default it should show as "checked". It does not.
  Selecting it from the menu has no effect. Our application worked fine
  with either build 4x (46 or 48?).
