A DESCRIPTION OF THE PROBLEM :
When using JOptionPane.showMessageDialog and similar methods, the resultant dialog now has a java cup icon displayed in the title bar. Also noticed this now appears in floating (undocked) toolbars so it could be an issue with JDialog.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Save the following application as Cup.java and compile and run on 1.6, then compare against earlier JRE versions:

public abstract class Cup {
  public static final void main(String[] args) {
    javax.swing.JOptionPane.showMessageDialog(null, "More tea vicar?");
    System.exit(0);
  }
}

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No icon in the title bar.
ACTUAL -
The Java cup icon is displayed.
