throw new UnsupportedTemporalTypeException("Invalid field " + field + " + for get() method, use getLong() instead");
has a "+" within the quotes resulting in the error message "UnsupportedTemporalTypeException: Invalid field ModifiedJulianDay + for get() method, use getLong() instead"

throw new UnsupportedTemporalTypeException("Invalid field " + field + " for get() method, use getLong() instead");
