[Hibernate-JIRA] Created: (HHH-2584) PersistentMap.remove() incorrect on uninitialized, non-extra-lazy map
by Daniel Wellman (JIRA)
PersistentMap.remove() incorrect on uninitialized, non-extra-lazy map
---------------------------------------------------------------------
Key: HHH-2584
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2584
Project: Hibernate3
Issue Type: Patch
Components: core
Affects Versions: 3.2.3, 3.2.2, 3.2.1
Environment: Hibernate 3.2.3 ga, MySQL 5.0.24a, for Win32
Reporter: Daniel Wellman
Attachments: persistentmap_remove.patch
This problem is nearly identical to HHH-2476: PersistentMap.put() incorrect on uninitialized, non-extra-lazy map. remove() has the same problem. See also issue HHH-2142.
The write up for HHH-2476 was so concise that I will transform it here, substituting remove() for put().
---
Essentially, an uninitialized PersistentMap loses the first remove() into it if defined as non-extra-lazy.
The underlying cause is the code in PersistentMap#remove() which attempts to readElementByIndex(). In the case of non-extra-lazy, readElementByIndex() returns the UNKNOWN marker object which is supposed to be used to signal that the delegate map is now initialized and to remove the element directly from the map. Long story short, PersistentMap#remove() does not properly check the return value from readElementByIndex() and react accordingly.

[Hibernate-JIRA] Created: (HHH-3030) NullPointerException happens in versioning

NullPointerException happens in versioning
------------------------------------------
Key: HHH-3030
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3030
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.5
Environment: any
Reporter: John
Priority: Minor
Here is the stack trace:
java.lang.NullPointerException

......
The code is:
public Object next(Object current, SessionImplementor session) {
return new Integer( ( (Integer) current ).intValue() + 1 );
}
Should there be a null checking for the object "current"?

[Hibernate-JIRA] Created: (HHH-3349) SequenceStyleGenerator generates strange IDs for PostgreSQL database
by Adam Wozniak (JIRA)
SequenceStyleGenerator generates strange IDs for PostgreSQL database
--------------------------------------------------------------------
Key: HHH-3349
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3349
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.6
Environment: hibernate-3.2.6.ga, hibernate-annotations-3.3.1.GA, hibernate-entitymanager-3.3.2.GA, hibernate-validator-3.0.0.GA, PostgreSQL 8.3.1 on Windows box. Sun Java 6 (Win32 on Vista 32 bits).
Reporter: Adam Wozniak
Hello
I've got a standalone application using environment:
* PostgreSQL 8.3.1 (Win 32)
* hibernate-3.2.6.ga
* hibernate-annotations-3.3.1.GA
* hibernate-entitymanager-3.3.2.GA
* hibernate-validator-3.0.0.GA
I've got a PostgreSQL database sequence:
CREATE SEQUENCE t_seq
INCREMENT 10
MINVALUE 1
MAXVALUE 999999999999999999
START 11;
My entity:
@Entity
@Table(name = "T")
@org.hibernate.annotations.Entity(dynamicUpdate=true, dynamicInsert=true)
public class T
{
private long id;
@Id
@Column(unique = true, nullable = false, precision = 18, scale = 0)
@GeneratedValue(generator = "t_generator")
@GenericGenerator( name = "t_generator",
strategy = "org.hibernate.id.enhanced.SequenceStyleGenerator",
parameters = {
@Parameter(name = "sequence_name", value = "T_SEQ")
, @Parameter(name = "increment_size", value = "10")
, @Parameter(name = "optimizer", value = "pooled")
}
)
public long getId()
{
return id;
}
public void setId(long id)
{
this.id = id;
}
}
And my test application to recreate this issue:
for(int i = 0; i < 11; i++)
{
if(i == 0 || i == 10)
System.out.println("Database hit to sequence will be performed.");
T t = new T();
em.persist(t);
}
Reading this Steve Ebersole description ( http://blog.hibernate.org/2082.lace#comments ) I would expect, that I will get the following IDs:
11
12
13
14
15
16
17
18
19
20
21
But Hibernate generates:
101
102
103
104
105
106
107
108
109
110
111
Is it something wrong with my code? Or this is a issue in Hibernate?
Note please, that on the same page ( http://blog.hibernate.org/2082.lace#comments ) other person claims that it doesn't work for his configuration based on PostgreSQL.
You will find my log4j output for my test application on the end of my email.

Adam Wozniak

[Hibernate-JIRA] Created: (HHH-3798) failure to lazy load a manyToOne and oneToMany mapped entity
by Ronald Kurz (JIRA)
failure to lazy load a manyToOne and oneToMany mapped entity
------------------------------------------------------------
Key: HHH-3798
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3798
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.3.1, 3.5
Environment: hibernate annotations test case, maven profile hsqldb, svn rev 16079
hibernate-core 3.3.1.GA, JBoss 4.2.3, SQLServer 2000
Reporter: Ronald Kurz
Attachments: test-case.tar.gz
Following situtation: an entity Data has Revision entities (oneToMany). Each Revision entity belongs to a Data entity. The Data entity has one manyToOne mapping to the current Revision. The mappings from Data to Revision are all lazy.
When loading a Data entity, which has two Revisions, the Revision entity which is also mapped as manyToOne (the current Revision for that Data entity), does not get loaded. It will be an uninitialized proxy, which is also resistent to Hibernate.initialize(<Data>.revision). The same proxy is also in the oneToMany mapped list.
@Entity
public class Data {
@Id @GeneratedValue
public int id;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "revisionId")
public Revision revision;
@OneToMany(mappedBy = "data")
public List<Revision> revisions = new ArrayList<Revision>();
}
@Entity
public class Revision {
@Id @GeneratedValue
public int id;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "dataId", nullable = false, updatable = false)
public Data data;
public Integer number;
}
The test case is written for the hibernate-annotations project (simply because I never wrote a mapping using xml)
