Depends on who you are and how much noise you make about the problem
and whether or not it is a problem or....details.

I've seen enterprise class applications written and run for extended
periods of time (days), dealing with huge amounts of data, that have
not suffered from slowness, much to the chagrin of Sun sales people
who realise they can't sell an E25K to run it.
So I don't accept that all Java programs are either slow or need to
consume 100s of megabytes of RAM for no reason. A poorly written
one may, yes. Maybe it is just easier to write applications (such
as Tomcat) that perform badly than it is to write good ones, in the
same way it is easy to write insecure PHP.
