      Description

      FULL PRODUCT VERSION :
      java version "1.6.0_13"
      Java(TM) SE Runtime Environment (build 1.6.0_13-b03)
      Java HotSpot(TM) Client VM (build 11.3-b02, mixed mode, sharing)

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows XP [Version 5.1.2600]

      A DESCRIPTION OF THE PROBLEM :
      Starting with Java 6 update 12, AppletContext.showDocument(URL u, String target) does not work in IE 7 if "target" refers to a window that is already open.

      No exception is thrown in the console, but the window referred to by "target" does not load the given URL.

      If no window with the same name as "target" is currently open, a new IE window is open and is loaded with the given URL.

      The same call is working fine in Firefox 3.0.8, using the same Java version.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. Compile the attached WindowRedirector.java code.
      2. Copy WindowRedirector.class, index.html, and appwindow.html to a web server.
      3. Browse to index.html using IE 7 on Windows XP SP 3 with Java 6 update 13 installed. Disable all pop-up blockers.
      4. Enter some name in the "Change this window's name to" text field, and click the "Change" button.
      5. Click the "Open Redirector" button.
      6. In the smaller browser window that comes up, the WindowRedirector applet will be running. Enter the name you chose in step (4) in the "Window name" field, and some URL in the "URL" field.
      7. Click the "Redirect" button.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The window whose name was changed in step (4) should load the URL entered in step (6).
      ACTUAL -
      Nothing happens. The window named in step (4) does not change locations.

      REPRODUCIBILITY :
      This bug can be reproduced always.
