spring-data-2.0.6 java.lang.IllegalArgumentException: Couldn't find PersistentEntity for type class HibernateProxy

Question

Spring data is failing when attempting to access an associated HibernateProxy instance (lazy fetched association).

Error with these latest versions:

spring-data-2.0.6.RELEASE
org.hibernate:hibernate-core:5.3.0.CR2

Entity Attribute with:

@Entity @Table(name = "WORKSPACE", uniqueConstraints = @UniqueConstraint(columnNames = { "EXT_KEY", "SERVICE_ID" })) public class Workspace {

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "SERVICE_ID", nullable = false, insertable = false, updatable = false)
public Service getService()

Lazy fetched associated entity Results in a HibernateProxy instance which fails with the following error:

java.lang.IllegalArgumentException: Couldn't find PersistentEntity for type class xxx.xxx.xxx.xxx.xxx.Service$HibernateProxy$zKdvHMKB!

Works with earlier versions

spring-data-1.5.12.RELEASE
org.hibernate:hibernate-core:5.0.4.Final

Temporary workaround - set the associated entity fetch type to EAGER

@ManyToOne(fetch = FetchType.EAGER)

Just wondering hw this class structure and annotated - Couldn't find PersistentEntity for type class xxx.xxx.xxx.xxx.xxx.Service ? It says cant find persistent entity. Can you post some snippet? — Karthik R
I suspect this is related to jira.spring.io/projects/SPR/issues/SPR-16569 can you downgrade to an older Hibernate version? — Jens Schauder
@KarthikR - added annotations to question - however I think Jens Schauder has solved it. — Nathan Coast
@JensSchauder - yes - you've identified it thanks! it's the switch from javassist to ByteBuddy in Hibernate 5.3 that is incompatible with spring. I'll follow up with the details / workaround. — Nathan Coast

Known incompatibility between spring-data and hibernate 5.3 https://jira.spring.io/projects/SPR/issues/SPR-16569

Solution 1) downgrade hibernate version to 5.2 or earlier.

Solution 2) set hibernate to use javassist instead of ByteBuddy

hibernate.bytecode.provider=javassist

Thanks Jens Schauder
