> URL: https://issues.apache.org/jira/browse/TUSCANY-2843
> Project: Tuscany
> Issue Type: Bug
> Components: Java SCA Assembly Model
> Affects Versions: Java-SCA-1.4
> Reporter: Shu Chao Wan

> Conformance item ASM60016 says that
> " the operations on the target interface of a wire MUST be the same as or be
> a superset of the operations in the interface specified on the source "
> In order to verify it with negative way, I wrote the following test case.
