> This JIRA is raised since Tuscany Java SCA fails the OASIS SCA Assembly 
> testcase
> ASM_4007_TestCase.
> The failure is manifested by an exception at runtime when a Reference is 
> invoked, where a null databinding is reported.
> The testcase involves 3 level of composites - Top level (A), middle tier (B) 
> and bottom level (C). A has a component that hsa B as its implementation and 
> B has a component with C as its implementation and C contains a single 
> component with a Java POJO implementation.  The Java POJO has a single 
> reference, which is successively promoted to the top level and is wired to a 
> target service at the top level, through a reference target on the component 
> in A.
> The significant feature of the arrangement is that the reference is declared 
> explicitly with a Java interface in C, but in B and in A the reference is 
> explicitly declared with an equivalent WSDL interface (the WSDL is a direct 
> translation of the Java).
> The failure occurs because of the WSDL interface on the Composite Reference 
> in B - chaning this for a Java interface, or removing the explicit 
> declaration from this place makes the error go away.
