      Description



      Name: ooR10001 Date: 01/05/2001


      javax.swing.JComponent.remove() method fails when the attempt to invoke it
      in appletviewer is made. It causes unexpected
      java.security.AccessControlException
      in jdk version b46. It needs to be fixed.

      Following test demonstrates this bug:
      ----------------------------------------------
      --- test.java ---
      import javax.swing.JFrame;
      import javax.swing.JPanel;

      public class test extends java.applet.Applet {

        public void init() {
            JFrame f = new JFrame();
            JPanel p = new JPanel();
            f.getContentPane().add(p);
            f.setVisible(true);
            f.getContentPane().remove(p);
            f.dispose();
            System.out.println("OKAY");
        }
      }
      --- test.html ---
      <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.X//EN">

      <html>
        <head>
          <title>Test</title>
        </head>

        <body>
            <h1>Test</h1>
            <p> <hr>
            <applet
              code="test"
              codebase="."
              width=400 height=350
            >
            </applet>

        </body>
      </html>
