<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:11.0pt">We did a few of these sort of cleanup fixes a year or so ago.<br>
<br>
In general, this sort of cleanup *might* be useful, but also causes some code churn and takes review cycles to ensure that there is no unintentional side effect.<br>
<br>
The last two might be OK cleanup tasks, but I wouldn't make them a high priority. Worth noting is that a seemingly redundant null check or instanceof check is not always a bad thing, so I wouldn't clean up all of them.<br>
<br>
The first group is the more interesting one. In some cases a potential null access can highlight actual bugs. However, I oppose any automated solution for these, since adding a null check where you don't expect a null (even if you IDE thinks it might be possible)
can hide the root cause of a problem.<br>
<br>
We aren't going to enforce these, though, so you'll likely need to configure your IDE to be less picky.<br>
