/**
 * Checks if the field is a valid date. If the field has a datePattern
 * variable, that will be used to format <code>java.text.SimpleDateFormat</code>.
 * If the field has a datePatternStrict variable, that will be used to
 * format <code>java.text.SimpleDateFormat</code> and the length will be
 * checked so '2/12/1999' will not pass validation with the format
 * 'MM/dd/yyyy' because the month isn't two digits. If no datePattern
 * variable is specified, then the field gets the DateFormat.SHORT format
 * for the locale. The setLenient method is set to <code>false</code> for
 * all variations.//from  w  w  w.  j  a v a2 s  . c  om

 * @param bean      The bean validation is being performed on.
