NullPointerException at runtime enhancement when the entity has no package
--------------------------------------------------------------------------
Key: OPENJPA-1003
URL: https://issues.apache.org/jira/browse/OPENJPA-1003
Project: OpenJPA
Issue Type: Bug
Affects Versions: 1.2.0
Environment: DB2, openJPA 1.2.0-r422266:683325
Reporter: Julien Kronegg
Priority: Minor
The given entity (referenced as <class>C</class> in the persistence.xml)
produce a NullPointerException at runtime enhancement:
// no package
@Entity
@Table(...) // valid table definition
public class C {
private int id;
@Id
@Column(...) // valid column definition
public int getId() {
return this.id;
}
public void setId(int id) {
this.id=id;
}
}
The NPE is :
org.apache.openjpa.enhance.ManagedClassSubclasser.setDetachedState(ManagedClassSubclasser.java:299)
org.apache.openjpa.enhance.ManagedClassSubclasser.configureMetaData(ManagedClassSubclasser.java:217)
org.apache.openjpa.enhance.ManagedClassSubclasser.prepareUnenhancedClasses(ManagedClassSubclasser.java:139)
org.apache.openjpa.kernel.AbstractBrokerFactory.loadPersistentTypes(AbstractBrokerFactory.java:310)
org.apache.openjpa.kernel.AbstractBrokerFactory.initializeBroker(AbstractBrokerFactory.java:228)
org.apache.openjpa.kernel.AbstractBrokerFactory.newBroker(AbstractBrokerFactory.java:190)
The class is enhanced like a charm when adding a package name.
I would expect either:
1) allow the enhancement of entities without package name [preferred]
2) receive an error message such as "could not enhance an entity without
package name".
I set the priority to "Minor" as this is not very likely that an entity is
added without package.
