Java SE (Java Platform, Standard Edition)

I develop a number of Web Start applications, and in most cases I have the application create shortcuts on the desktop. These normally work correctly. As you know, on MS-Windows, the Javaws shortcuts point to a cached JNLP and cached ICO file.

The problem occurs after some time ... eventually for some reason the cache clears the ICO file. The desktop icon then appears as a "missing icon".

This makes JavaWS applications feel very "unprofessional" to users. No other Windows apps have icons that disappear seemingly at random.

My questions:
(1) does anyone know of a workaround to this problem?
(2) has the JavaWS team ever considered fixing this problem? It can't be hard to fix.
