title: JUNIT 5 test classes not running sequentially
body: <p>What am I doing wrong? Why can't I set up methods to work in parallel and classes in series?</p>
  <p>i use settings parallel in my POM:</p>
  <pre><code>                    &lt;configurationParameters&gt;
                          junit.jupiter.execution.parallel.enabled = true
                          junit.jupiter.execution.parallel.mode.default = concurrent
                          junit.jupiter.execution.parallel.mode.classes.default = same_thread
                          junit.jupiter.execution.parallel.config.strategy = fixed
                          junit.jupiter.execution.parallel.config.fixed.parallelism = 6
                      &lt;/configurationParameters&gt;
  </code></pre>
  <p>but when i call the top level maven goals in Jenkins: <code>clean -Dtest=*ParallelTest test</code> (start six test classes)</p>
  <p>then I have six classes running in parallel at the same time:</p>

  <p>I tried experimenting with same_thread/concurrent, concurrent/concurrent, but only the line works -  <code>junit.jupiter.execution.parallel.config.fixed.parallelism = 6</code>.I can only control the number of threads but not the parallel execution of methods or classes in any settings. But the lines <code>mode.default</code> and <code>mode.classes.default</code> Maven does not seem to see.
  In all Parallel classes I have the annotation <code>@Execution(ExecutionMode.CONCURRENT)</code></p>
