Compile and run this program (jedsize.Demo):


package jedsize;
import java.awt.*;
import javax.swing.*;

public class Demo
{
  public static void main (String[] args)
  {
    makeFrame (true);
    makeFrame (false);
  }

  public static void makeFrame (boolean editable)
  {
    JFrame frame = new JFrame();
    Container cont = frame.getContentPane();

    JEditorPane edit = new JEditorPane ("text/html", "some text");
    edit.setEditable (editable);
    System.out.println ("editable: "+editable);
    System.out.println ("prefsize: "+edit.getPreferredSize());

    cont.add (edit);
    frame.pack();
    frame.show();
  }
}

It makes two JFrames, each with a JEditorPane viewing HTML text, one
editable, one not, and prints each preferred size to System.out. The
non-editable one gets a height of 6.

I would guess this has something to do with JEditorPane's special
preferred size rules when inside a viewport, combined with the fact
that this particular JEditorPane was put in a plain old JPanel.
(There's a reason I can't use this inside a JScrollPane for the
purpose I have in mind.) I couldn't tell for sure, though, from
looking at the source code.
