Caused by: org.hibernate.AnnotationException: Illegal attempt to map a non collection as a @OneToMany, @ManyToMany or @CollectionOfElements:

I have a problem, when I run hibernate it shows me the error of "Caused by: org.hibernate.AnnotationException: Illegal attempt to map a non collection as a @OneToMany, @ManyToMany or @CollectionOfElements: com.trein.Moneda.documento" , and the truth is I do not know why it is throwing this error. It seems like its failing in Moneda.java class

Documento.java

@ManyToOne
@JoinColumn(name = "pais_id", nullable = false)
private Pais pais;

@ManyToOne
@JoinColumn(name = "moneda_id", nullable = false)
private Moneda moneda;

@ManyToOne
@JoinColumn(name = "remesa_id", nullable = false)
private Remesa remesa_doc;

Moneda.java

@OneToMany(mappedBy = "moneda")
private Documento documento;

if you are expecting that Moneda object has many Documento object then you should make it List<Documento> because @OneToMany annotation expects the property to be a collection of some objects.
