CountTest causes lambda Ser/Derialization tests to fail

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.
