>             Project: Tuscany
>          Issue Type: Bug
>          Components: Java SCA Core Runtime
>    Affects Versions: Java-SCA-2.0

> If I have:
> o a <component/> in a composite which uses a Java POJO as its implementation, 
> o that POJO has a reference, which is declared with @Reference(required=false), so that the reference multiplicity is 0..1
> o the <component/> leaves the <reference/> unwired (by any means)
> the current code injects a Proxy into that reference - a Proxy that is unwired, and which causes an exception when invoked.
> This is incorrect behaviour.  An unwired 0..1 reference should cause the injection of null into the reference in the POJO and the POJO should be able to test for this null at runtime and so avoid calling the reference.
> The test which revealed this problem is the OASIS Assembly testcase ASM_12006_TestCase
