Description

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.
