Review Comment:
I'm a little confused. The difference method only return a set of property
in property name set (which is user configure) but not in field names set
(which is RocketMQ Configuration Item). So I think it will correctly record the
invalid property name set in user's configuration file.
I have some test case in ``MixAllTest.java``, It would be better explain
that when logging will be missed if you could give me some clearly test case.~
