#977 Cannot derive instance of class CIM_IndicationSubscription

When we try to create an indication subscription instance we run into the problem, that during derive instance the jsr48 client insists on the reference class names for properties to be exactly those classes that are specified in the class definition. It does not accept subclass for reference properties.
But in the case of indication subscriptions, the handler property will usually be a reference to a subclass of CIM_ListenerDestination, such as CIM_ListenerDestinationCIMXML.
Since the java client is not able to determine the inheritance relationship of classes to allow for proper type checking of reference parameters, I propose to relax the type checking for reference properties.
Attaching a patch that I have been using as workaround so far.
