Description
A NullPointerException occurs in DefaultCompositeActivator.createWires() when a composite's SCDL specifies a component reference with a target attribute referring to a composite reference. This is invalid in SCA 1.0.
The test case org.apache.tuscany.sca.itest.sdodatabinding.DatabindingTestCase has this error in greeter.composite.vm (see revision 536691 of /incubator/tuscany/java/sca/itest/databindings/sdogen/src/main/resources/generate). This error in the test case has been reported as TUSCANY-1255.
The runtime error occurs because the model contains a service object with no InterfaceContract. Here's the stack trace:
