Domain Configuration — JaVers Documentation
The object diff algorithm is the core of JaVers. When two objects are compared, JaVers needs to know what type they are. We distinguish between the following types: Entities, Value Objects, Values, Containers, and Primitives.

I found the correct way to do this. I had been using Jackson ObjectMapper for serialization/deserialization which was giving me problems.
To properly serialize and deserialize I had to use Javers' internal JsonConverter:
Diff diff = javers.compare(myObject1, myObject2)
//Tears and pain :(
String omDiff = objectMapper.writeValueAsString(diff)
Diff fromOm = objectMapper.readValue(omDiff, Diff.class)
//yay :)
String jcDiff = jsonConverter.toJson(diff)
Diff fromJc = jsonConverter.fromJson(jcDiff, Diff.class)

Currently, we are working on the feature called shadows. https://github.com/javers/javers/issues/133. So you would be able to restore your orginal domain objects from snapshots persisted in JaversRepository. But restoring original objects from diffs is not possible since diffs captures only a change between two states.
