Class Annotation does not implement a equals method and therefor inherits
equals(*) from Object. StyledString.equals(*) fails for two strings
with identical text and identical attribute names with identical attribute
values wrapped in Annotations. TextAttributeSet is used to hold attributes.

Test code follows:

   public Status equalsAnnotation() {
   
      StyledString aStyledString, anotherStyledString;
      AttributeSet anAttributeSet;
      AttributeSet anotherAttributeSet;
   
      // wrap same value in annotations
      anAttributeSet = new TextAttributeSet("One", new Annotation("1") );
      anotherAttributeSet = new TextAttributeSet("One", new Annotation("1") );
      aStyledString = new StyledString("A", anAttributeSet);
      anotherStyledString = new StyledString("A", anotherAttributeSet);
      if (!anotherStyledString.equals(aStyledString) ) {
         return Status.failed("equality fails for equal values wrapped in annotations");
      }
