Jukka Zitting commented on JCR-2929:
------------------------------------
The benefit of that change is improved iteration performance, but are any of
these cases things where performance boost is notable or even measurable? If
not, I would rather leave the code as is since the required Map.Entry syntax is
rather verbose. AFAIUI Angela already reverted some of these changes.
More generally, unless there are obvious correctness, performance or other
clear benefits to an improvement like this, the exact code patterns are often a
matter of style and personal preference. In such cases I'd leave it up to the
original author to decide what the code should look like.
