      orig synopsis: "getAlignment() in HiddenTagView does not provide correct values"
      28 Nov 2000, eval1127@eng -- still present in current merlin sources.
      -------------
      java version "1.3.0" (and merlin)
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
      Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)

      package: javax.swing.text.html;
      filename: HiddenTagView.java

      have a look at the method "protected Component createComponent":

      protected Component createComponent(){
       ...
      updateYAlign(font);
      ...
      }

      and now have a look at the method "void updateYAlign(Font font)":

      void updateYAlign(Font font) {
      FontMetrics fm = Toolkit.getDefaultToolkit().getFontMetrics(font);
      float h = fm.getHeight();
      float d = fm.getDescent();
      float yAlign = (h - d) / h;
      }

      all the vars are created locally in the method! So the method
      has no effect. I think the declaration of "float yAlign" is
      a mistake in this method because the InstanceVar "yAlign" is
      not affected by this method. ( "yAlign" is initially set to "1",
      so the getter method - getAlignment - will always return "1" ).

      So the Solution will be:

      void updateYAlign(Font font) {
      FontMetrics fm = Toolkit.getDefaultToolkit().getFontMetrics(font);
      float h = fm.getHeight();
      float d = fm.getDescent();
      yAlign = (h - d) / h;
      }
