Spring Improve Javadoc in InstantiationAwareBeanPostProcessor

Post-process the given property values before the factory applies them to the given bean If I understand correctly, AbstractAutowireCapableBeanFactory#applyPropertyValues represents the factory applies them to the given bean. So, suggest adding the method link in Javadoc to make the documentation clearer.

Thanks for the PR and sorry it took so long to process it. You are right but AbstractAutowireCapableBeanFactory is an implementation detail and I am not keen to add a reference to it in the interface contract.
