Sure go ahead, but I do think the wording is a little odd.
Maybe something like: 'Can not clear the cache at this time. If the 
problem persists, try closing your browser & JNLP applications.'

I do not know if we should be telling people to kill all java 
applications, really. Up to you though if you want to keep it in.
