    `String` | `getProperty()` Returns a failed property of the failure source object.
    `String` | `toString()` Returns a String representation of the failure.

    `static ValidationFailure` | `validateMandatory(Object bean, String attribute, Object value)`
    `static ValidationFailure` | `validateNotEmpty(Object bean, String attribute, Collection<?> value)` Returns a ValidationFailure if a collection attribute of an object is null or empty.
    `static ValidationFailure` | `validateNotEmpty(Object bean, String attribute, String value)` A utility method that returns a ValidationFailure if a string is either null or has a length of zero; otherwise returns null.

      A utility method that returns a ValidationFailure if a string is either null or has a length of zero; otherwise returns null.

    - #### validateJavaClassName

          public static ValidationFailure validateJavaClassName(Object bean,

      A utility method that checks that a given string is a valid Java full class name, returning a non-null ValidationFailure if this is not so. Special case: primitive arrays like byte[] are also handled as a valid java class name.
      Since:
        1.2

    - #### getProperty
