+/**
+ * <pre>
+ * Javadoc to @{@link Basic} :
+ * The use of the Basic annotation is optional for persistent fields and properties of these types.
+ * If the Basic annotation is not specified for such a field or property, the default values of the Basic annotation apply.
+ *
+ * And the property :
+ *
+ * <code>boolean optional() default true;</code>
+ *
+ * But if we add the @Basic annotation or not on a boolean type, we do not get the same result.
+ * In one case, the boolean is optional, while in the other, it is not, which contradicts the Javadoc.
