      Description

      some of hotspot tests still use java.util.Random or Math.random directly, to make tests execution more deterministic it's better to use Utils.getRandomInstance() in all such tests.

      it also makes sense to adopt 'randomness' k/w (used in jdk test suite), so it will be easier to identify tests whose behavior might vary from run to run.
