Using @JoinColumnsOrFormulas and mappedBy

Question

Using @JoinColumnsOrFormulas and mappedBy

I have a problem with the following code:

FiBean table:

@JoinColumnsOrFormulas({ 
    @JoinColumnOrFormula(column = @JoinColumn(name = "TRI", referencedColumnName = "TRI", nullable = false, insertable = false, updatable = false)),
    @JoinColumnOrFormula(formula = @JoinFormula(value = "USER1", referencedColumnName = "CODE"))
})
private UserBean user1;

UserBean table:

@OneToMany(mappedBy="user1", cascade={CascadeType.PERSIST, CascadeType.MERGE})
private Collection<FiBean> listeUser1;

Then this error occurs:

Caused by: java.lang.ClassCastException: org.hibernate.mapping.Formula

I found a workaround here ( https://forum.hibernate.org/viewtopic.php?f=1&t=1010559 by removing mappedBy on the UserBean) but why doesn't this code work?
