[hibernate-issues] [Hibernate-JIRA] Commented: (EJB-401) @OneToOne or @ManyToOne references an unknown entity when maven-surefire-test runs without -DforkMode=none property

[Farrukh Najmi (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/EJB-401?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=31712#action_31712 ] 

Farrukh Najmi commented on EJB-401:
-----------------------------------

If this is a classloader issue as I suspect then perhaps someone could look at my hibernate dependencies and their versions to see if it is possible that there is a duplicate older version of some hibernate code that had a bug in this area that has been fixed in a newer version. If so please indicate what jar I should remove.

> maven-surefire-plugin defines its forkMode property as follows at <http://maven.apache.org/plugins/maven-surefire-plugin/test-mojo.html>:
> forkMode  	String  	Option to specify the forking mode. Can be "never", "once" or "always". "none" and "pertest" are also accepted for backwards compatibility. Default value is once.
> I am baffled as to why hiberante EntityManager is behaving working when forkMode is set to "none" but fails when forkMode is set to default of "once".
> It seems like a classloader related issue. Here are the hibernate related jars in my webapp:
> org.hibernate:hibernate-search:jar:3.0.1.GA
> org.hibernate:hibernate:jar:3.2.6.ga
> org.hibernate:hibernate-entitymanager:jar:3.3.2.GA
> org.hibernate:hibernate-commons-annotations:jar:3.0.0.ga
> org.hibernate:ejb3-persistence:jar:1.0.1.GA
> org.hibernate:hibernate-annotations:jar:3.3.1.GA
