In EclipseLink you could use a @BasicCollection for this. You would use a
EnumTypeConverter to convert the Enum. This mapping uses a separate table
to store the values.
You could also just serialize the collection to a binary field, but this
would not allow querying.
You could also instead change the Enum to a class and make it an Entity and
define a OneToMany or ManyToMany to it.
