---------------------------

             Summary: argument type mismatch error randomly occured
                 Key: OPENJPA-2446
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2446
             Project: OpenJPA
          Issue Type: Bug
          Components: Enhance, jdbc, kernel
    Affects Versions: 1.2.3, 1.2.2

            Reporter: hm
            Priority: Critical


We are using an embedded class as Id :
@Entity
@Table(name = "GC5REQUESTLOG")
@DataCache(enabled = false)
public class RequestLogDA implements java.io.Serializable {

	// Fields
	@EmbeddedId
	@AttributeOverrides({
			@AttributeOverride(name = "srvcLogID", column = @Column(name = "G5005ID")),
			@AttributeOverride(name = "srvcLogDate", column = @Column(name = "G5005DATE")),
			@AttributeOverride(name = "requestID", column = @Column(name = "G5008ID")) })
	private RequestLogIdDA id;
....
}
@Embeddable
public class ResponseLogIdDA implements java.io.Serializable {

	@Column(name = "G5005ID", nullable = false, precision = 12, scale = 0)
	private Long srvcLogID;

	@Column(name = "G5005DATE", nullable = false, length = 7)
	private Date srvcLogDate;

	@Column(name = "G5008ID", nullable = false, precision = 6, scale = 0)
	private Integer requestID;
.....
}

sometimes we see following error in log files.
