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
