wildfly-11.0.0.Final JPA

I am deploying to above. I get this error message:

{"jboss.persistenceunit.registrar#REGDB" => "org.hibernate.AnnotationException: Property no.tobiassenit.sipstack.sip.message.AbstractMessage.part has an unbound type and no explicit target entity. Resolve this Generic usage issue or set an explicit target attribute (eg @OneToMany(target=) or use an explicit @Type Caused by: org.hibernate.AnnotationException: Property no.tobiassenit.sipstack.sip.message.AbstractMessage.part has an unbound type and no explicit target entity. Resolve this Generic usage issue or set an explicit target attribute (eg @OneToMany(target=) or use an explicit @Type"}

,

I have this code:

@OneToOne(optional = true, cascade = CascadeType.ALL, targetEntity = AbstractPart.class)
@JoinColumn(name = "PART", unique = false, nullable = true, updatable = false)
protected X part;

What about the target= vs the targetEntity=? There is no target attribute or @Type annotation available.
