In the section of 3.3.1 in spring framework version 5.1.3.RELEASE core technologies document, the document describes that there is a getPropertyValues method. In fact, there is no such method in the BeanWrapeer class. I'm not sure if this is a version problem or refers to a method in another class instead of BeanWrapper.

It looks like that was getPropertyValue(s) at some point, i.e. meant to refer to all overloaded variants, but was edited in https://github.com/spring-projects/spring-framework/commit/395e3d008cc3fa63dbfc7319fad0f29120e84053#diff-7e1586ca210f63b9665d58ea71268244L233 and has been that way since 5.1.
