RFR of JDK-8176563: @since value errors in apis of java.base/java.logging module

[Roger Riggs]

Hi,

- The @since in ObjectInputFilter.checkInput is unnecessary; the class 
has @since 9

- java.util.Properties.replace @since seems unnecessary because it will 
not be seen.
   The @hidden is a bit odd too but that has its own explaination (btw, 
it is the only one in the jdk).

- I agree about not needing @since on overrides of existing methods.
    Even for toString() though in some cases the javadoc now has useful 
info about the toString contents.

Regards, Roger
