All of the dialogs created by Deployment code in JDK7 are extra large - sometimes bigger than the screen.
This happens either when running plugin or webstart from JDK7 with JDK7 jre, and does not happen when running plugin or webstart from JDK7 with JDK6 jre.

It can also be seen in the following simple stand alone test case.
The testcase uses the UITextArea class from deployment. If there is somethine we are doing wrong there please show us:


import java.awt.*;
import javax.swing.*;
import javax.swing.border.*;

public class Test1 {

    public Test1() {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                JDialog dialog = new JDialog((Dialog) null, true);

                dialog.setTitle ("this is a test");

                dialog.getContentPane().setLayout(new BorderLayout());
                UITextArea t1 = new UITextArea();
                UITextArea t2 = new UITextArea();
                t1.setText("This is the text that goes on top");
                t2.setText("This is the text that goes on right");


                dialog.getContentPane().add(t1, BorderLayout.NORTH);
                dialog.getContentPane().add(t2, BorderLayout.EAST);

                JPanel pan = new JPanel();


                dialog.getContentPane().add(pan, BorderLayout.SOUTH);
