Fix issue where GnssMeasurements wouldn't allow empty measurements.

            throw new InvalidParameterException("Parameter 'clock' must not be null.");

        }

        if (measurements == null || measurements.length == 0) {

            throw new InvalidParameterException(

                    "Parameter 'measurements' must not be null or empty.");

            mReadOnlyMeasurements = Collections.emptyList();

        } else {

            Collection<GnssMeasurement> measurementCollection = Arrays.asList(measurements);

            mReadOnlyMeasurements = Collections.unmodifiableCollection(measurementCollection);

        }

        mClock = clock;

        Collection<GnssMeasurement> measurementCollection = Arrays.asList(measurements);

        mReadOnlyMeasurements = Collections.unmodifiableCollection(measurementCollection);

    }
