/**
 * Description of SUREFIRE-1080: <br>
 * <br>
 * There are 9 tests in total in the attached project, and mvn test will show 9 tests run.
 * When I use the command " mvn test -Dparallel=classes -DforkCount=2 -DuseUnlimitedThreads=true", it shows 13 tests
 * run (and sometimes 16), and some tests are run more than once.
 * If I remove forkCount, or parallel, everything will be fine. But it is problematic when combining together.
 * Apache Maven 3.2.2-SNAPSHOT
 * Surefire 2.18-SNAPSHOT
 * JUnit 4.11
