title: Wrong parallel run in JUnit 5
body: <p>I'm trying to set up a parallel test run for my project. So, here is a screenshot, where you can see JUnit 5 settings</p>

  <p>According to <code>junit.jupiter.execution.parallel.config.strategy</code> and <code>junit.jupiter.execution.parallel.config.fixed.parallelism</code> settings, I was expecting that there are would be just 2 threads for the run. But as you can see in console output there are 4 different threads.</p>
  <p>What do I need to make JUnit run a bunch of tests just with 2 threads ?</p>
