I'm having some problems with Redis / Jackson integration, and I'm unsure if it's a bug in the code, or something I've configured incorrectly.
It appears that null values, and collections are not correctly mapped.
I've created a gist[1] with a suite of tests that show the problems I'm having.
In summary, here's an example:
This test fails with:
java.lang.IllegalArgumentException: Can not construct instance of java.lang.Long from String value 'null': not a valid Long value
at [Source: N/A; line: -1, column: -1] (through reference chain: com.mangofactory.example.EntityWithId["id"])
The other examples of failures are :
Could someone please advise if this is a bug, or if I've configured (something) incorrectly?

Code:
@Test
public void nullLongIsHandledCorrectly()
{
DecoratingStringHashMapper<EntityWithId> mapper = mapperOf(EntityWithId.class);
EntityWithId entity = new EntityWithId();
// Encode & decode
Map<String, String> hash = mapper.toHash(entity);
EntityWithId decoded = mapper.fromHash(hash);
assertThat(decoded, notNullValue());
assertThat(decoded.getId(), nullValue());
}
@Data
public static class EntityWithId
{
Long id;
String otherField = "Hello"; // so there's something to serialize

- Lists of Enums encoded as [FOO], instead of ["FOO"]
- Lists of strings not decoding correctly
- Empty lists not decoding correctly
Could someone please advise if this is a bug, or if I've configured (something) incorrectly?
