Simon Nash commented on TUSCANY-1912:
-------------------------------------
The NullPointerException is caused by the name of the promoted composite
reference (MyService) being different from the name of the component reference
(myService). If the name of the promoted composite reference is changed to
myService, I get a different failure:

To complete the set (for now), if I then change the value of the "promote="
attribute from "MyClientComponent/myService" to just "MyClientComponent" (a
valid shorthand), I get another different error as follows:
org.osoa.sca.ServiceUnavailableException: No service invoker is available for
reference myService (bindingURI=null operation=someMethod).
