Message Title

Caching query results in a spring JPA repository using query-hint, hibernate throws SerializerException when the entity involved has Enum field and a customer converter. In org.hibernate.cache.spi.QueryKey there is a field org.hibernate.transform.CacheableResultTransformer which is not transient. It seems like this field is causing the exception.
