/**
 * This is the BeanInfo object for the TestBean class. It acts as a "stopper"
 * for the introspector: we don't want it to look at properties defined at this
 * or higher classes.
 * <p>
 * Note this is really needed since using Introspector.getBeanInfo with a stop
 * class is not an option because:
 * <ol>
 * <li>The API does not define a 3-parameter getBeanInfo in which you can use a
 * stop class AND flags. [Why? I guess this is a bug in the spec.]
 * <li>java.beans.Introspector is buggy and, opposite to what's stated in the
 * Javadocs, only results of getBeanInfo(Class) are actually cached.
 * </ol>
