    Thread t2 = asyncCopy(process.getErrorStream(), stderr, cLatch);
    process.getHandler().bytesMessage(makeStream(3, OUTPUT_EXIT0.getBytes(StandardCharsets.UTF_8)));
    cLatch.await();
    process.destroy();
    assertEquals(msgData, stdout.toString());
    assertEquals(errData, stderr.toString());
