[jira] [Updated] (ARIES-843) Bean can not be created if constructor argument use generics

["Tomas Forsman (Updated) (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ARIES-843?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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="exampleBean" class="example.ExampleImpl"/>

<bean id="proxyServiceInitialization" class="example.Service">
    <argument ref="exampleBean"/>
</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.
