In JPA 2.0 annotations, there I feel a misperception about nullable columns.
There are two annotations to set a property to be nullable or not.
@Column(nullable = true) & @Basic(optional = true)
What is the difference of these two in setting a filed nullable/not-nullable?
There exists situations that I see both annotations are held on a property/field with a value set to false.
