-------------------------------------
The reported error is still valid but the patch here can be ignored as the
patch for TUSCANY-2884 committed all the test cases together at revision:
752817
> [1.x] NPE occurs when doing negative test about conformace item 60008

> Key: TUSCANY-2883
> URL: https://issues.apache.org/jira/browse/TUSCANY-2883
> Project: Tuscany
> Issue Type: Task
> Components: Java SCA Assembly Model
> Affects Versions: Java-SCA-1.4
> Reporter: Shu Chao Wan
> Attachments: composite.patch

>
> In ASM60008, it says that "The interfaces of the component references
> promoted by a composite reference MUST be the same, or if the composite
> reference itself declares an interface then all the component reference
> interfaces must be compatible with the composite reference interface.
> Compatible means that the component reference interface is the same or is a
> strict subset of the composite reference interface."
> In order to verify this statement in negative way, I wrote a composite file
> whose promoted component interface is incompatible with the composite
> reference's interface, one is CService, and the other is BService, and then a
> ServiceRuntimeException is expected as the result. But actually I got a
> NullPointerException.
