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