J2SE Version (please include all output from java -version flag):
   1.4.0-beta_refresh-b72

Does this problem occur on J2SE 1.3? Yes / No (pick one)
   No

Operating System Configuration Information (be specific):
   Windows98/WinNT (Solaris as well), but works fine on Win2K.

Hardware Configuration Information (be specific):
   Pentium, 750MH, 256MB

Bug Description:
  The "removeNotify" is not called for a component when IE with a JApplet
  which contains that component is closed.

  Problem: if component opens/creates a Window/Dialog/JDialog/etc. and
  tries to close it (clean after yourself on possible exit), then there
  is no way to find out when that exit occurs.
  As a result, the IE hangs-up.

Steps to Reproduce (be specific):

  1. compile attached RemoveNotifyBug.java
  2. Start applet through RemoveNotifyBug1.html in IE5.
  3. Enable swing-java-console.
  4. Click on JLabel to open JDialog.
  5. Close the browser, but NOT a DIALOG!!!
   NOTE: since console may be closed and
   you may miss final outputs, instead of
   close-browser, you may use the "Refresh"
   button. Though, in this case you may get
   an exception (at least I have), I suspect
   it happens due to restart-timing problems
   in plug-in or in browser.

  Problem can be reproduced under the following configuration:

  - Install 1.3.1 first and 1.4 later on WinNT machine, "removeNotify"
    does not show on Java console. It did show on Win2K, but
    NullPointerException exception throws sometime(see below), but at least
    browser does not hang.

  - works fine if you only install 1.4.
  - Install 1.4 first and 1.3.1 later, it works fine if you set 1.4 version
    JRE through plugin control panel. If you set 1.3.1 JRE, then the applet
    does not appear but plugin seems to try to load applet-rectangle
    though without background.

NullPointerException exception message on Java Console:
