Description

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.

composite file
--------------------------------------------------------------------------------------
<component name="FComponent">
<implementation.java class="org.apache.tuscany.sca.vtest.assembly.composite.impl.FServiceImpl"/>
<reference name="d">
<interface.java interface="org.apache.tuscany.sca.vtest.assembly.composite.DService" />
</reference>
<reference name="c">
<interface.java interface="org.apache.tuscany.sca.vtest.assembly.composite.CService" />
</reference>
</component>
<component name="CComponent">
<implementation.java class="org.apache.tuscany.sca.vtest.assembly.composite.impl.CSubServiceImpl"/>
<service name="CSubService">
<interface.java interface="org.apache.tuscany.sca.vtest.assembly.composite.CSubService"/>
</service>
</component>
<component name="DComponent">
<implementation.java class="org.apache.tuscany.sca.vtest.assembly.composite.impl.DSubServiceImpl"/>
<service name="DSubService">
<interface.java interface="org.apache.tuscany.sca.vtest.assembly.composite.DSubService" />
</service>
</component>

<wire source="FComponent/d" target="DComponent" />
<wire source="FComponent/c" target="CComponent" />
------------------------------------------------------

Here, CSubService is a subset of CService and DSubService is a subset of DService

TestCase
------------------------------------------------------
public void ASM60016_n() throws Exception

{ initDomain("subinterfacewire.composite"); FService fservice = ServiceFinder.getService(FService.class, "FComponent"); Assert.assertEquals("DProperty", fservice.getGreetings("")); Assert.assertEquals("Some State", fservice.getString("")); cleanupDomain(); }

---------------------------------------------------------

And I got NullPointerException here instead of expected ServiceRuntimeException.
