Java SE (Java Platform, Standard Edition)

I have posted before a topic related to this matter, although now I have a lot more information about what is going on (although still no fix for it). This is the link to the earlier post, containing JVM HOTSPOT EXCEPTION_ACCESS_VIOLATION

http://forum.java.sun.com/thread.jspa?threadID=5116970&messageID=9402346#9402346

The issue is that after deploying on Windows XP a multi threaded, memory consuming (40 Mb) Java Swing application using Java Web Start, and the standard web page (IE6) reference to the jnlp file to launch the installation from Tomcat, each time this application gets executed by double clicking on the desktop icon (with no IE6 interaction at all), calls start being made between jvm.dll (sun) and jscript.dll (Microsoft IE), these interactions never release the memory they consume, so after a period of using the application it crashes unavoidably. If I execute exactly the same application launching it from command line (no Web Start nor IE6 browser involved), the application works nicely all the time, no problem at all.

My question is: does anyone know why these calls to jscript.dll are even being made during web start application execution? As said, it's a desktop Swing app, it does not need the browser at all, and jscript.dll is a IE dll. Anyone can advice on how these interactions can be eliminated?

I've worked with Microsoft support for two weeks on this issue and all they have said is that it is a Sun problem and they can not help further.

Thanks
