The recently added stream test for counting is serialization hostile and results in lambda SAND test failures.

The test can be updated to obtain the expected size using:

  long expectedCount = data.size();

For SAND tests, the following:

        AtomicLong expectedCount = new AtomicLong();
        data.stream().forEach(e -> expectedCount.incrementAndGet());

will result in expectedCount being 0 on deserialization.
