Java applet crashes IE 6 (Windows XP SP2) when running on 1.5.0_14.
The problem is not reproducible on 1.5.0_13.

The problem is very well reproducible, although not strictly, both on
single and dual processor machines.

1. Test case
------------
Please run attached test case AHS.zip on 1.5.0_14:

- uncompress AHS.zip
- cd AHS
- open StartaAHS.html in IE
  1. click on the link to start AHS.
     a separate window will open. 
     it shows a single tab named "Ärendeinfo"
  2. close windows after initiated
- Repeat steps 1+2 until IE will crash (10 - 15 iterations most likely are enough)


2. hs_err_pid.log

use 1.5.0_13

The parent associated should be a component of an owned window last / currently active instead of the the last/current proxied.
