Key class conflict with OneToOne relation
Using JBoss-4.2.2.GA.
Using a uni-directional OneToOne Relation between two entities with a composite PK.
First class:
@Entity
@IdClass(value=MbiMsgpa.PK.class)
@Table(name="mbi_msgpa")
public class MbiMsgpa implements java.io.Serializable
{
@Id
@Column(name="msghd_serial")
private java.lang.Integer msghdSerial;
@Id
@Column(name="part_no")
private java.lang.Integer partNo;
@Column(name="message_type")
private java.lang.String messageType;
@Column(name="source")
private java.lang.String source;
/** Field line. */
@Column(name="line")
private java.lang.Integer line;
@Column(name="time_created")
private java.util.Date timeCreated;
@Column(name="bp_task_id")
private java.lang.Integer bpTaskId;
@OneToOne(cascade=CascadeType.ALL,fetch=FetchType.LAZY)
@JoinColumns({
@JoinColumn(name="msghd_serial",referencedColumnName="msghd_serial",insertable=false,updatable=false),
@JoinColumn(name="part_no",referencedColumnName="part_no",insertable=false,updatable=false)
})
private MbiMsgpt mbiMsgpt;
....
Second class is
@Entity
@IdClass(value=MbiMsgpt.PK.class)
@Table(name="mbi_msgpt")
public class MbiMsgpt implements java.io.Serializable
{
@Id
@Column(name="msghd_serial")
private java.lang.Integer msghdSerial;
@Id
@Column(name="part_no")
private java.lang.Integer partNo;
...
Using this, I get exceptions like this:

Using MbiMsgpa.PK as the ID-class instead of MbiMsgpt.PK for Entity MbiMsgpt solves the problem.
Is this somewhere documented as the expected behaviour for this or may I call this a Bug?
