    Description

      So far, BeanUtils does not support indexed or mapped properties of Map object (PropertyUtilsBean.getPropertyOfMapBean(Map bean, String propertyName) )
      and throw IllegalArgumentException.

      For instance if you have Map<String, String[]> and you want to get property by calling propName[0] (or propName(0)), method isIndexed (isMapped) of DefaultResolver returns true which raises previously mentioned exception. From my point of view it seems that method gets data which needs and is possible to parse propertyName to get desired result.

      E.g. something similar to:

      if (resolver.isIndexed(propertyName)) {
   String name = resolver.getProperty(propertyName);
   int idx = Integer.valueOf(resolver.getIndex(propertyName)); // handle NumberFormat exception by your way
   return ((Object[]) bean.get(name))[idx]; // handle ArrayIndexOutOfBounds and ClassCast exception by your way
}

      I was a bit surprised that I didn't find this issue in existing ones. I'm sorry if there is any which I omitted.
      Is it possible that this funcionality will be provided in any future release? Thank you
