Probably when hibernate session is used, it creates empty hibernate proxy instance for lazy loaded fields. Therefore, it causes lazy load exception or n+1 select problem when using model mapper deep copying.

Example usage for intercepter:

mapper.getConfiguration().setResolveSourceValueInterceptor(source -> {
    if (emFactory.getPersistenceUnitUtil().isLoaded(source)) {
            return source;
    }
    return null; // return null when hibernate field is not fetch from database (lazy loading)
});

The problem solution has been provided based on the issue here #97.
