/**
 * <ul>
 * Verify that logs of new notifications, when sendNotification is invoked,
 * write to file. File name is value of descriptor of
 * ModelMBeanNotificationInfo.
 * <li>Create java class, which is not MBean. MBean has 1 getter and 1
 * setter methods.
 * <li>Create ModelMBeanNotificationInfo object for my type with descriptor
 * with logging.
 * <li>Create ModelMBeanInfoSupport object. All ModelMBeanXXXInfo except
 * ModelMBeanNotificationInfo are default.
 * <li>Create RequiredModelMBean object.
 * <li>Instance of java class in 1st step sets managed resource for
 * RequiredModelMBean using setManagedResource method.
 * <li>Send my notification using sendNotification method.
 * <li>Verify that logfile was created and size of file > 0.
