Rick Curtis resolved OPENJPA-1003.
----------------------------------

       Resolution: Cannot Reproduce
    Fix Version/s: 1.2.0
         Assignee: Rick Curtis

Unable to recreate the NPE. Tested on:
OpenJPA 1.2.0
version id: openjpa-1.2.0-r422266:683325
Apache svn revision: 422266:683325

Perhaps the problem was with one of your other annotations?

> 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.
