null field in pojo causes JsonGenerationException: error: expecting end array

[jjspiegel]

Here is the reproducer:

        Movie movie = new Movie();
        movie.setName("The Godfather");
        movie.setGross(BigDecimal.valueOf(246120974));
        movie.setGenre("Drama");

        OsonFactory factory = new OsonFactory();
        ObjectMapper mapper = new ObjectMapper(factory);

        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        mapper.writeValue(baos, movie);
        baos.close();

        // The Movie represented as OSON binary JSON
        byte[] oson = baos.toByteArray();

        Movie movie2 = mapper.readValue(oson, Movie.class);

        System.out.println("Title: " + movie2.getName());
        System.out.println("Genre: " + movie2.getGenre());

The Movie class can be found here:
https://github.com/oracle/json-in-db/blob/master/JdbcExamples/src/main/java/movie/model/Movie.java

Since the images field of movie is null, it causes this exception:
