Details:

Steps to reproduce:
1. Compile and run the attached testcase.

Expected results:
1. A window shows up. It has a textarea with "text1".

Actual results:
1. No window is shown and the testcase throws the following exception:
java.lang.NegativeArraySizeException
   at javax.swing.text.AbstractDocument$BranchElement.replace
(AbstractDocument.java:747)
   at javax.swing.text.PlainDocument.removeUpdate (PlainDocument.java:136)
   at javax.swing.text.AbstractDocument.remove (AbstractDocument.java:294)
   at javax.swing.text.JTextComponent.setText (JTextComponent.java:1016)
   at textarea.<init> (textarea.java:9)
   at textarea.main (textarea.java:4)


Testcase:
import javax.swing.*;
public class textarea extends JFrame {
        public static void main(String[] args) {
                (new textarea()).show();
                }
        public textarea() {
                JTextArea textarea = new JTextArea(10, 40);
                textarea.setText("text0\n");
                textarea.setText("text1\n");
                this.setContentPane(textarea);
                this.pack();
        }
}


Note that "text0" works but "text0\n" (with newline) does not.
