>
> This issue was fond after running IT tests "CheckTestNgGroupThreadParallelIT"
> of Maven Surefire Project.
> The CPU was fully overloaded which was maybe precondition in this issue.
> The problem is that the TestNG runs test methods in parallel and the
> TestSetRunListener crashes.
> The field "reportEntries" in the class "TestSetStats" referenced ArrayList.
> This collection is not thread-safe which means that the retrieval of the
> elements is not guaranteed.
> The elements are added in TestSetStats#finishTest(). The elements are never
> null, see the TestSetRunListener#testSucceeded() which passed a newly created
> instance of WrappedReportEntry from wrap().
> Caused by: java.lang.NullPointerException
