I investigated the issue. Here is the root cause:

src/main/resources/META-INF/sca/SpringDelegationHelloWorld-context.xml defined two Spring beans that implement the same remotable java interface HelloWorld. After the java introspection, we end up
with two services with the same name "HelloWorld" in the componentType that represents the spring context.
