                 Key: LUCENE-3986
                 URL: https://issues.apache.org/jira/browse/LUCENE-3986
             Project: Lucene - Java
          Issue Type: Sub-task
          Components: general/test
            Reporter: Dawid Weiss
            Assignee: Dawid Weiss
            Priority: Minor
             Fix For: 4.0


Robert asked for it. Calling random() (and its methods) can obscure memory visibility issues (because random() is thread local, context-sensitive, etc.). An option (or randomly selected mode) of running with a simple Random (static/ test method level only) would simulate the framework as it was before (reading -- possibly non-reproducible thread races but at the same time testing memory visibility issues in the core code).
