Strange Jackson exception being thrown when serializing Hibernate object

Answer 1

I had a similar problem with lazy loading via the hibernate proxy object. Got around it by annotating the class having lazyloaded private properties with:

@JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})

I assume you can add the properties on your proxy object that breaks the JSON serialization to that annotation.

Avoid Jackson serialization on non fetched lazy objects
