I am assuming you have a @ManyToOne realationship in the Entity you are trying to delete. On the @OneToMany side you most likely have | @OneToMany(cascade = CascadeType.ALL, .....) | If you change to @OneToMany(cascade = {CascadeType.MERGE,CascadeType.REMOVE}, ....) It may solve your problem, at least it did for me. You will have to work out if this will affect your application before doing so.
