Neeraj Joshi commented on IMPERIUS-29:
--------------------------------------

To import  multiple instances of the same class you should use a syntax as
follows:
Import Class java.util.Map:props1,props2;

> Policy importing multiple instances of same class can not be evaluated
(Java)

> But a change like this is not always acceptable.
