Re: [eclipse-pmc] Review of mass changes

Hi Andrey,

thanks for following up on my suggestion, even though you put a
different spin to it.

As I said several times in the Gerrits, my understanding was that your
advice to use empty only for the positive case and size()>0 for the
negative ones.

To also give an example why I had this impression, here is a quote

>From Andrey:
Lars, I have no clue why do you change perfectly readable .size() > 0
with less readable ! .isEmpty(). Can we please stop this? Especially
there is no one reviewing every line, and as we see there can be
possible bugs coming out of this mass changes.

As I tried to explain, I disagree with the approach to use as mixed
approach of empty/ size in our code and asked you to go to PMC if you
want to change that.

Also in our Gerrit discussion I explained to you that the usage of
empty was already addressed before by you to the PMC and that the PMC
decided that empty is better than size. Please see again here, your
previous thread and for
example Danis reply

I agree with improving readability and I think I reacted to every
single content based feedback you gave. I think your feedback is
valuable and would like to continue to see it.

To give another quote, this time from
>From Lars:
I think you are suggesting to use empty only in the positive case. If
that is your suggestion, yes you have to try convince others that this
is good idea.

If you do code review, than please avoid general statements, which can
be be misunderstood. Feedback to improve these changes is very much

To the second topic:

We can discuss in the next PMC call, but my personal opinion is that
we should focus our review activities on critical code changes not on
trivial changes. And putting additional review restriction, without
providing additional capacity may be hard to archive.

Best regards, Lars
