+/**
+ * <p>Static helper class that is used to lookup SCA references and inject them into objects

+ *
+ * <p>Methods and fields may be public, protected, package-access or private. If they are not
+ * public an attempt is made to call {@link Method#setAccessible(boolean)} in order to make
+ * them accessible from this class. If the attempt fails, an exception will be thrown.</p>
+ *
+ * <p>Method names can take any form. For example {@code setSomeBean(Bean b)} or
+ * {@code someBean(bean b)}. In both cases, if a specific Reference name is not supplied,
+ * the default name of {@code someBean} will be used.</p>
+ *
+ * <p>The value of the {@code @Reference} annotation should be the reference on the
+ * SCA component with an {@code <implementation.web>} componentType.
+ *
+ * <p>The first time that any of the injection methods in this class is called with a specific type
+ * of object, the object's class is examined for annotated fields and methods. The discovered
+ * fields and methods are then cached for future usage.</p>
