There are two such diagnostics: one for collection methods and one for
equals(). See
<https://www.eclipse.org/eclipse/news/4.7/jdt.php#unlikely-argument-types>
for more information about these two new diagnostics.
For each of these diagnostics, I've set the severity level to
"warning" in projects that have some instances of the suspicious code,
or to "error" in projects that have no instances of the suspicious
code.
These should mostly be things that we've already decided earlier that
we explicitly don't want to "fix" because they simply disagree with
the WALA project's coding style.
The additional diagnostics are ones that were previously being
ignored, but which we seem to have been ignoring by default rather
than as a conscious choice.
For diagnostics of which we currently have *zero* instances, treat
these as errors rather than merely warnings. The intent is to
permanently lock out future regressions of things we've completely
fixed. In the future, whenever we fix the last instance of a given
warning in a given Eclipse project, we should also promote that
diagnostic to an error to keep things clean into the future.
The "potentially" qualifier is here because these methods are visible
outside the WALA source tree. These methods may seem OK to be static
based on the code we have here, but we have no way of knowing whether
third-party code expected to be able to subclass and override. I'm
going to play it safe and assume that we want to allow that.
Note that we are still allowing Eclipse warnings about methods that
can *definitely* be declared static; a different configuration option
controls these. For private methods, final methods, and methods in
final classes, if the code seems static-safe based on what we have
here, then that's good enough: we don't need to worry about
third-party overrides.
In general, the WALA code base is not really ready for nullness
checking. It would be nice if we got there some day, but I'm not
planning to take that on now or any time soon. Until then, it's not
useful to warn about missing @NonNullByDefault declarations on WALA
packages.
