--------------------------------------
I created ARIES-1063 for this issue a few days ago, however I am not sure which
of the two provided patches is better...
> Blueprint - ServiceFactory can't be specified as the bean class
> ---------------------------------------------------------------
>
> Key: ARIES-1065
> URL: https://issues.apache.org/jira/browse/ARIES-1065
> Project: Aries
> Issue Type: Bug
> Components: Blueprint
> Reporter: Simon Gormley
> Attachments: blueprint_servicefactory.patch
>
>
> Specifying a class that implements org.osgi.framework.ServiceFactory as the
> bean class causes an error indicating that the class does not implement the
> specified interfaces.
> e.g. a blueprint.xml containing:
> <?xml version="1.0" encoding="UTF-8"?>
> <blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";>
> <bean id="MyServiceImplBean" class="com.code.impl.MyServiceFactory"/>
> <service ref="MyServiceImplBean" id="MyServiceImplBeanService"
> interface="com.code.api.MyServiceInterface"></service>
> </blueprint>
> Where MyServiceFactory implements ServiceFactory and can be used to obtain
> the actual service class that implements the MyServiceInterface would cause
> an error indicating that MyServiceFactory does not implement
> MyServiceInterface (which is true)
> Suggested fix (patch attached) is to ensure for this case that the proxy
> class indicates it implements the ServiceFactory interface, and then delay
> validation until after the service is obtained.
