In lists.firewalls you write:

I agree with the 2nd statement. Java is just a programming language 
and from what little I've read a reasonable one.  Now Java applets.... 
yes there is a problem.   I suspect though that if the applet viewers
(ie. browsers et al) were able to verify the origin on an applet - eg
if applets could be signed by an X.509 cert (like we use for SSL)
the situation would improve somewhat.

I'd be reasonably happy if I could configure my browser to run only 
applets signed by my company's CA.

But of course...

Indeed.
