ConcurrentTestRunner does not work with ErrorCollector rule

[David Mas]

When one test using ErrorCollector fails, all the following tests report the same failure. I have created a small snippet to demonstrate this.
You can play with the test names to affect ordering and change the runner.

Runner	Test order	Expected	Actual
default	failing 1st	fail, pass	fail, pass
default	failing last	pass, fail	fail, pass
concurrent	failing 1st	fail, pass	fail, 🔴fail
concurrent	failing last	pass, fail	pass, fail

import com.anarsoft.vmlens.concurrent.junit.ConcurrentTestRunner;
import org.hamcrest.Matchers;
import org.junit.FixMethodOrder;
import org.junit.Rule;
import org.junit.Test;
import org.junit.rules.ErrorCollector;
import org.junit.runner.RunWith;
import org.junit.runners.MethodSorters;
import static org.junit.Assert.assertTrue;

// Fixed test order. Rename test0 to test_ to see the change
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
// Change to default runner and the result is the expected in any test order.
@RunWith(ConcurrentTestRunner.class)
public class TestErrorCollector {

  @Rule
  public ErrorCollector errors = new ErrorCollector();

  @Test
  public void test1() {
    assertTrue(true);
  }

  @Test
  public void test0() {
    errors.checkThat(1, Matchers.equalTo(2));
  }

}
