Mike Edwards resolved TUSCANY-3013.
-----------------------------------
Resolution: Fixed
Resolved with the code committed in
773349
- mainly with an update to ComponentReferenceEndpointReferenceBuilderImpl to
check for non-Callback binding.sca references which have no autowire, targets
or @uri.
> Java POJO with reference marked as multiplicity 0..1 is given a reference
> proxy even when the reference is unwired

> Key: TUSCANY-3013
> URL: https://issues.apache.org/jira/browse/TUSCANY-3013
> Project: Tuscany
> Issue Type: Bug
> Components: Java SCA Core Runtime
> Affects Versions: Java-SCA-2.0
> Reporter: Mike Edwards
> Assignee: Mike Edwards
> Fix For: 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
