Description

2-level inheritance (C extends B extends A) leads to crash.

This ticket is related to ~~GRAILS-7794~~.

I have 3 classes as follows:

public abstract class HibernateDAO implements Serializable {
    // implementation of equals, hashCode, toString
}

@Entity
@Table(name = "JOB_", schema = "CONFIGURATION",
		uniqueConstraints = @UniqueConstraint(columnNames = { "CODE" }))
@Inheritance(strategy = InheritanceType.JOINED)
public class Job extends HibernateDAO {
	private Integer id;
	private String code;

	@Id
	@Column(name = "ID", nullable = false, precision = 8, scale = 0)
	@GeneratedValue(generator = "SCHEDULE_SEQ", strategy = GenerationType.SEQUENCE)
	@SequenceGenerator(name = "SCHEDULE_SEQ", sequenceName = "configuration.schedule_seq", allocationSize = 1)
	public Integer getId() {
		return id;
	}

	public void setId(Integer id) {
		this.id = id;
	}

	@Column(name = "CODE", nullable = false, length = 64)
	public String getCode() {
		return code;
	}

	public void setCode(String code) {
		this.code = code;
	}
}

@Entity
@Table(name = "INBOUND_COLLECTOR_JOB", schema = "CONFIGURATION")
@PrimaryKeyJoinColumn(name = "JOB_ID")
public class InboundCollectorJob extends Job {
	private Boolean autoLaunchOutboundFlow;

	@Column(name = "AUTO_LAUNCH_OUTBOUND_FLOW", nullable = false)
	public Boolean getAutoLaunchOutboundFlow() {
		return autoLaunchOutboundFlow;
	}

	public void setAutoLaunchOutboundFlow(Boolean autoLaunchOutboundFlow) {
		this.autoLaunchOutboundFlow = autoLaunchOutboundFlow;
	}
}

Both, Job and InboundCollectorJob are defined in hibernate.cfg.xml.

During running of grails run-app I observe crash as shown below.
After removing Job-HibernateDAO inheritance (changed to class Job implements Serializable) entities are processed without crash.

Project attached as requested.
After changing definition of Job to:
Job implements Serializable
app will start.
BTW, sample for ~~GPGORMJPA-15~~ want to create and attach tomorrow.

Correct file attached once again with name TwoLevelInherit1a.zip - to avoid naming confusion.
