> 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
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> 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.
