NPE in BaseWireBuilderImpl with reference bindings that specify URIs

Wed, 21 May 2008 13:11:03 -0700

After some fun debugging today I realized that something has changed in how reference bindings are configured, breaking with an NPE on references with bindings that specify URIs, like follows: 

<composite targetNamespace="http://catalog"; name="catalog-mediation">
  <component name="MediatedVegetablesCatalog">
    <implementation.java
     class="services.mediation.VegetablesCatalogMediationImpl"/>
    <service name="Catalog">
      <interface.java interface="services.Catalog"/>
      <binding.ws name="Catalog"
       uri="http://localhost:8105/MediatedVegetablesCatalog"/>
    </service>
    <reference name="catalog">
      <interface.java interface="services.ejb.CatalogEJBRemote"/>
      <binding.ejb name="catalog#VegetablesCatalogEJB/CatalogEJB"
       uri="corbaname:iiop:[EMAIL PROTECTED]:1050#VegetablesCatalogEJB"/>
    </reference>
  </component>
</composite>
Instead of seeing an EJB binding in the memory model representing the reference, I'm now seeing an SCA binding, with no URI, causing the following NPE:

Any clue?
