Description

Hi, guys.

Suppose I have a Map, let's call it "building", inside that map I have an entry
with key "rooms", which is a Collection. If I try to access room number 20 like
this:

"building.rooms[20].type" it doesn't work (throws IllegalArgumentException).

I made a custom implementation of "building" Map so that I can see what param is
passed to the get() method. Surprisingly I see, that
PropertyUtilsBean.getInstance().getProperty(bean, name) calls get() method on my
Map with parameter "rooms[20]" (including index part).

This is definitely a bug, because getProperty() should recognize, that "rooms"
is an indexed property (because it has []), so it should cut off "[20]", call
get("rooms") and then obtain element with index 20 from the retrieved Collection.

Please have a look.
