Hi,
We are experiencing an issue in our application that only occurs under load - we sometimes fail to read entities from the database.
I've isolated this issue to a fairly simple test case (please see attached eclipse project). I have some test entities listed below. When I run a load test that creates, reads and updates these entities in multithreaded application it sometimes fails to read them from the DB with "No matching results for a unique query" error. The error occurs in 2-3% of iterations. When I run the same test in a single thread it is 100% successful.
I'm using version 2.3.7.
Test entities:
@Entity
@Inheritance(strategy=InheritanceType.TABLE_PER_CLASS)
@TableGenerator(name="TestIdTableGen", initialValue=0, allocationSize=50)
public class TestIdHolder implements Serializable{
private static final long serialVersionUID = 1L;
private long version;
private long longId;
@Id
@GeneratedValue(strategy=GenerationType.TABLE, generator="TestIdTableGen")
public long getLongId() {
return longId;
}
public void setLongId(long longId) {
this.longId = longId;
}
@Version
public long getVersion() {
return version;
}
}
@Entity
@Indices({
@Index(members={"oidId", "type"}),
@Index(members={"parentAcl"})
})
public class TestEntity extends TestIdHolder {
private static final long serialVersionUID = 6249921651146397564L;
@OneToOne(cascade=CascadeType.REFRESH, fetch=FetchType.EAGER)
private TestEntity parentAcl;
@Basic
private boolean entriesInheriting = true;
private long oidId;
private String type;
............................
Kind regards,
Natalia Levine.
