Hello, I won't argue it is good or not, it's just not in line with bean specs. However blueprint specs says: #factoryMethod - A static or instance factory method name that corresponds to a publicly accessible method on the given class or factory manager.
So it's not pointing to return value of the factory method. To be honest, it's not important for me how this combination might be done - it might be done just like we did this in Spring - with MethodInvokingFactoryBean. But I wish to don't copy unnecessary code when it might be done in existing. WDYT?
