NPE when component reference has target composite with custom implementation
----------------------------------------------------------------------------
Key: TUSCANY-1260
URL: https://issues.apache.org/jira/browse/TUSCANY-1260
Project: Tuscany
Issue Type: Bug
Components: Java SCA Model
Affects Versions: Java-SCA-0.90
Environment: Windows XP
Reporter: Ignacio Silva-Lepe
Fix For: Java-SCA-0.90
A NPE occurs in DefaultCompositeActivator.createWires() when component
reference has target composite with custom implementation. This used to work
before the last refactor.
