[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-3030) NullPointerException happens in versioning
[
http://opensource.atlassian.com/projects/hibernate/browse/HHH-3030?page=c...
]
Gail Badner resolved HHH-3030.
------------------------------
Assignee: Gail Badner
Resolution: Rejected
This is expected behavior. If an entity is mapped as having a version property, then
Hibernate assumes that existing entities will have a non-null version.
The database representation needs to be consistent with what is mapped.
Hibernate only allows unsaved entities to have a non-null version.
Please move further discussion to the user forum (https://forum.hibernate.org/).
Thanks,
Gail
NullPointerException happens in versioning
------------------------------------------
Key: HHH-3030
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3030
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.2.5
Environment: any
Reporter: John
Assignee: Gail Badner
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"?
