+ * when the component is initialized.  If the annotation is

+ * tools are required to examine all superclasses of any component
+ * class to discover all uses of this annotation in all superclasses.
+ * All such annotation instances specify resources that are needed

+ * appear on private fields and methods of superclasses; the container
+ * is required to perform injection in these cases as well.
