BeanRegistrationExcludeFilter

public class AbstractBeanDefinitionExcludeFilter
extends java.lang.Object
implements BeanRegistrationExcludeFilter

Keeps abstract bean definitions out of ahead-of-time processing.

An abstract definition is a template: it carries property values for children to inherit and is never instantiated. Spring's bean-definition code generator has no representation for that — it emits neither the abstract flag nor a bean class, so the definition is regenerated as a concrete bean of type Object carrying the template's properties, which fails as soon as the context applies them.

Children are unaffected: ahead-of-time processing generates them from their merged definition, so inherited values are already folded in and no parent is needed at runtime. A definition contributed dynamically still finds its parent, because the post-processor that registers the template runs during refresh in an ahead-of-time context as it does in any other.
