When using inheritance throw exception java.lang.NoSuchFieldError: __odbTracker on NetBeans 7.3 + ObjectDB 2.5.1 + Jboss 7.1.1, but works fine on NetBeans 7.3 + ObjectDB 2.5.1 + GlassFish 3.1 

@Entity
public class Person extends AbstractObject {
    private static final long serialVersionUID = 1L;

    @ManyToOne @Index
    private City city;

     @OneToMany(mappedBy = "owner")
    private List<City> cities;

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public City getCity() {
        return city;
    }

    public void setCity(City city) {
        this.city = city;
    }

    public List<City> getCitys() {
        return cities;
    }

    public void setCitys(List<City> citys) {
        this.cities = citys;
    } 
}



@Entity
public class City extends AbstractObject {
    private static final long serialVersionUID = 33L;

    @OneToMany(mappedBy = "city")
    private List<Person> persons;

    @ManyToOne @Index
    private Person owner;

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public List<Person> getPersons() {
        return persons;
    }

    public void setPersons(List<Person> persons) {
        this.persons = persons;
    }

    public Person getOwner() {
        return owner;
    }

    public void setOwner(Person owner) {
        this.owner = owner;
    }
}

@Entity
public abstract class AbstractObject implements IAbstractObject {
    //private static final long serialVersionUID = 1L;
    @Id
    private String id = UUID.randomUUID().toString();

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    @Override
    public int hashCode() {
        int hash = 0;
        hash += (id != null ? id.hashCode() : 0);
        return hash;
    }

    @Override
    public boolean equals(Object object) {
        // TODO: Warning - this method won't work in the case the id fields are not set
        if (!(object instanceof AbstractObject)) {
            return false;
        }
        AbstractObject other = (AbstractObject) object;
        if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) {
            return false;
        }
        return true;
    }

    @Override
    public String toString() {
        return "test.AbstractObject[ id=" + id + " ]";
    }
}

This code throw exception:

Person person = new Person();

person.setName(name);

City city = new City();

city.setName("Москва");

person.setCity(city);

entityManager.persist(city);

entityManager.persist(person);

The exception:

if remove the inheritance works fine. On GlassFish 3.1 with inheritance also works fine.

Why "person.setName(name);" works fine? But "city.setName("Москва");" throw exception

Thanks for your help.

如果有人对答案感兴趣 - objectdb 支持

我在 build.xml 中添加了这段代码。该项目工作正常。

<target name="-post-compile">
    <java classname="com.objectdb.Enhancer" fork="true" classpath="C:/projects/test/lib/objectdb.jar">
        <arg line="-s ./build/classes/test/*.class"/>
    </java>
</target>
