Description

Entity with 1xm relationship define in orm.xml causes the following exception during emf.createEntityManager.

+ //Removing the XML from the orm.xml file, and using this fixes the issue:
+ //@OneToMany(fetch=FetchType.LAZY,cascade=CascadeType.ALL)
+ private List<XMLManyToOneEntity> xmlManyToOneList = new ArrayList<XMLManyToOneEntity>(0);

And this mapping in the orm.xml:

+ <one-to-many name="xmlManyToOneList" fetch="LAZY">
+ <join-column name="IDENTITY" />
+ <cascade>
+ <cascade-all/>
+ </cascade>

<openjpa-2.2.0-SNAPSHOT-r422266:1235624 fatal user error> org.apache.openjpa.persistence.ArgumentException: You have supplied columns for "org.apache.openjpa.persistence.arrays.model.XMLOneToManyEntity.xmlManyToOneList", but this mapping cannot have columns in this context.
