ParallelParameterized - how to save test results in parallel for each input in same order as input?

@RunWith(ParallelParameterized.class)
public class RoutingResponseShortRegressionOneByOne {

    private int numberOfProcessedRequests;
    private Object currentRequestIndexLock = new Object();


    @Test
    public void compareNewResponseToBaselineReturnsNoLargeDifferences() throws IOException {

        int currentRequestIndex;
        synchronized (currentRequestIndexLock) {
            //currentRequestIndex = e2EResultShort.completeRoutingResponses.size();
            currentRequestIndex = numberOfProcessedRequests;
            numberOfProcessedRequests++;
        }

I try to run this code

and I see numberOfProcessedRequests == 0 in every run, and doesn't increment as I would expect from class member.

It's a ParallelParameterized Test.

Why does it create a new Test Class instance for every input?

I see the ctor is called only once.

Should there be a different way to run the test in parallel for each input and still maintain the order of the results as the order of the input?
