The problem is unstable execution time of java programs:

Why? Given that computers are pretty determinstic, I'd argue that you
don't have the same conditions from run to run.
Did you make experiments or it's your theoretical conclusion :) ?
Have done experiments. I never claim that it's the same conditions
every run. That's the issue, I think.

Try to create an application that runs 20 seconds and run it several times.
Frankly, I do not exactly know why. But I know a lot of reasons that could
affect this dispersion. For example, there is a number of serving
threads and GC that impact on execution time.
