Spring Error in Bean Definition Inheritance example in ref docs

In the Bean Definition Inheritance example in the reference docs, when I used instance code, an error occurred.

Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'age' of bean class [org.springframework.beans.DerivedTestBean]: Bean property 'age' is not writable or has an invalid setter method. Did you mean 'name'?

The age's setter method is consistent with the configuration.

When I comment out the age attribute, it runs successfully.

For the example to work, DerivedTestBean either needs to extend TestBean, or they need to both have compatible name and age JavaBean properties.

I assume your implementations of DerivedTestBean and TestBean do not adhere to that.

For working example types, see the corresponding classes in this package in our test suite.

In light of that, I am closing this issue.
