> A PolicyConfigurationException may be raised incorrectly when using operation
> policy as shown in the example below.
> <composite ...>
> <component ... requires='A'>
> <implementation.java class="test.MyServiceImpl"/>
> <service name="MyService">
> <operation name="setXYZZY" requires="B"/>
> </service>
> </component>
> </composite>
> Let's say intent 'A' constrains an implementation rather than a binding.
> Constraints aren't examined until the final step of propagating the intents
> into the binding. So 'A' gets inherited by the service and then the service
> operation. Now the code in
> PolicyComputationUtil.addInheritedOpConfOnBindings gets control to inherit
> the service operation intents to the binding. If it can find a matching
> operation element under the binding, it goes through logic that applies the
> constraint (among among things). This would keep 'A' from being inherited by
> the binding level. However if it can't find an operation element under the
> binding, it simply adds a new operation element without doing any checking on
> it. This leads to a PolicyConfigurationException because there is no policy
> that applies to the binding and satisfies 'A'.
> I am attaching a patch that changes the logic in
> PolicyComputationUtil.addInheritedOpConfOnBindings so that added binding
> operations go through the same logic as existing operations.
