Um, scotch the stopwatch idea! :)

Interesting, I would want to see this, and the overall problem.

Perhaps. It may also be misconfig of the Xserver/card combo.

The JVM/JRE probably leaves this to local libraries.

>(BTW I'm looking for a reasonable Excel substitution, all candidates so far have been terribly slow and lacking features.StarOffice, Gnumeric etc. That led me to look at JAVA)
Excel, etc are applications, JAJVA is a programming language; you can't really 
draw equivalences here. A spreadsheet written in JAVA may be great, or it 
may be a poor performer based on the skills (or lack) and needs of the spread-
shhet implementor.

You need to find a JRE/JVM guru, I'm none such, but they exist.. maybe even 
here.
