@Uses annotation with a parameterized collection causes InstantiationException
------------------------------------------------------------------------------
Key: QI-33
URL: http://issues.ops4j.org/jira/browse/QI-33
Project: Qi4j
Issue Type: Bug
Affects Versions: 0.2
Reporter: Sonny Gill
Assignee: Rickard Öberg
Using @Uses with a parameterized Collection causes an exception.
This is most likely linked to http://issues.ops4j.org/jira/browse/QI-32
From what I can see the problem is at -
UsesInjectionProviderFactory (line 57)
if( resolution.getInjectionModel().getInjectionClass().isAssignableFrom(
usedObject.getClass() ) )
Here resolution.getInjectionModel().getInjectionClass() returns a String
whereas it should be ArrayList<String>
Test case
