        This handles Java primitive type equivalence and uses isAssignableFrom for all other types, with a bit of magic for native types and polymorphism i.e. Number assigned an int. If either parameter is null an exception is thrown

        Parameters:
        leftType - The type of the left hand part of a notional assignment
        rightType - The type of the right hand part of a notional assignment

        Looks for a property of the reference instance with a given name.

        If found its value is returned. We follow the Java bean conventions with augmentation for groovy support and static fields/properties. We will therefore match, in this order:

        1. Standard public bean property (with getter or just public field, using normal introspection)
        2. Public static property with getter method
        3. Public static field
        Returns:
        property value or null if no property found
        Throws:
        org.springframework.beans.BeansException
