Tibor Digana updated SUREFIRE-1114:
-----------------------------------
Description:
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
