Prior to this commit, and due to idiosyncracies of
java.beans.Introspector, overridden boolean getter methods were not
detected by Spring's ExtendedBeanInfo, which relied on too-strict
Method equality checks when selecting read and write methods.
Now ExtendedBeanInfo uses Spring's ClassUtils#getMostSpecificMethod
against the methods returned from java.beans.Introspector in order
to ensure that subsequent equality checks are reasonable to make.
