Turns out this issue may be a duplicate of a known issue, taking this over to
the dev list.

Subject: HHH-6044 and partial identifier generation - No part of a composite
identifier may be null HibernateException
[note this is an issue with sequences too]
Quoting
https://docs.jboss.org/hibernate/orm/5.4/userguide/html_single/Hibernate_User_Guide.html#identifiers-composite-nonaggregated
With non-aggregated composite identifiers, Hibernate also supports "partial"
generation of the composite values.
Example 135. @IdClass with partial identifier generation using @GeneratedValue
I seem to be having the same issues as
https://hibernate.atlassian.net/browse/HHH-6044
I have existing tables / Entities (simplified):
CREATE TABLE [cresaptown].[saar](
[id] [bigint] IDENTITY(1,1) NOT NULL primary key
);
@Entity
@Table(schema = "cresaptown", name = "saar")
public class SystemAccessAuthorizationRequest
{
@Id
@GeneratedValue
Long id;
}
CREATE TABLE [cresaptown].[signature](
[rid] [bigint] IDENTITY(1,1) NOT NULL,
[sid] [bigint] NOT NULL,
PRIMARY KEY ([rid],[sid]),
FOREIGN KEY([rid]) REFERENCES [cresaptown].[saar] ([id])
);
@Entity
@Table(schema = "cresaptown", name = "signature")
@IdClass(Signature.ID.class)
public class Signature
{
@Id
@Column(name = "sid")
@GeneratedValue
Long sid;
@Id
@JoinColumn(name = "rid")
@ManyToOne
SystemAccessAuthorizationRequest rid;
public static class ID implements Serializable
{
Long sid;
Long rid;
}
}
A code fragment
em.getTransaction().begin();
SystemAccessAuthorizationRequest saar = new
SystemAccessAuthorizationRequest();
em.persist(saar);
Signature sig = new Signature();
sig.setRid(saar);
em.persist(sig);
em.getTransaction().commit();
gives this exception, but if I disable the null check in
AbstractEntityTuplizer.getIdentifier, I get the same issue as in HHH-6044
