PCollectionViews$SimplePCollectionView.hashCode allocates memory

I'm currently profiling memory consumption of our Beam pipeline and have noticed that

    org.apache.beam.sdk.values.PCollectionViews$SimplePCollectionView.hashCode()

makes noticeable heap allocations. The implementation is:

    return Objects.hash(tag);

That itself translates to:

    return Arrays.hashCode(values);

Which performs implicit array creation in order to call:

    public static int Arrays.hashCode(Object a[]);

Instead of the helper call, doing simple:

    tag.hashCode();

Seems more appropriate.
