Once again, you show little mercy for the Sun customer.  Is it really 
wise to beat up customers in public?  It might be limiting to your 
career path at Sun, or at other companies.  Potential future employers 
will learn a lot about you via Google.

The problem with patching is that it causes down-time.  It sounds like 
Ethan's application can not afford any down-time and they are doing 
whatever they can to avoid it.  There is a trade-off between the cost 
of patching and rebooting the OS, and any the cost of any bugs which 
may become evident due to not patching.
