When running without the interactive console attached, for example in Jenkins, the output is noisy:

      [OK] o.o.j.t.coherence.varHandles.fields.volatiles.StringTest
(ETA: 00:00:04) (Rate: 1.63E+07 samples/sec) (Tests: 10434 of 10490) (Forks: 10434 of 10490) (Iterations: 62583 of 62940; 62583 passed, 0 failed, 0 soft errs, 0 hard errs)
                                                                                                                                                                              
      [OK] o.o.j.t.acqrel.varHandles.arrays.opaque.DoubleShortTest
(ETA: 00:00:04) (Rate: 1.63E+07 samples/sec) (Tests: 10435 of 10490) (Forks: 10435 of 10490) (Iterations: 62584 of 62940; 62584 passed, 0 failed, 0 soft errs, 0 hard errs)

jcstress should detect this and either disable progress indicator or make it less noisy.
