Tomas Forsman updated ARIES-843:
--------------------------------
Description:
If a bean has a constructor argument which use generics, the injection fails
with "org.osgi.service.blueprint.container.ComponentDefinitionException: Unable
to find a matching constructor".
Example:
package example;
public interface Example<A> {}
public class ExampleImpl implements Example<String> {}
public class Service {
private Example<String> example;
public Service(Example<String> example) {
this.example = example;
}
}
<bean id="exampleReference" class="example.ExampleImpl"/>
<bean id="proxyServiceInitialization" class="example.Service">
<argument ref="exampleReference"/>
</bean>
Changing the constructor of Service to "public Service(Example example)" make
it work, but it would be better to have it inject correctly with the generics
intact.
