In your case I'm not sure if cache was the reason. It seems moreover like some file conflict or I 
don't know. Non of my attempts to reproduce ended by hanging - all by ended by correct error dialog.

If more instances of netx are running then cleaning of cache will not succeed, and user will be

The reason why not to clear  cache automatically are offline stored jnlp apps.  But I admit itw is 
not correctly informing about those anyway.
So yes, some thinking in this direction will need to be done..
