Which collections are permissible for javax.persistence.ManyToMany

Researching I found that javax.persistence.ManyToMany relationship can be implemented various collection. I wonder if all java.util collections are permissible or if there are restrictions.

Note that I actually use Scal开发者_运维问答a and I love to use one of the immutable collections. But I guess that is out of the question.

In the Hibernate Documentation it only says:

You can map Collection, List, Map and Set pointing to associated entities as one-to-many or many-to-many associations using the @OneToMany or @ManyToMany annotation respectively. If the collection is of a basic type or of an embeddable type, use @ElementCollection. We will describe that in more detail in the following subsections.
