@NotNull vs @Nonnull


#1

The latter appears to be standard but it seems kotlin only recognises the IntelliJ-specific former form? Is that intentional or a bug?

It would be nice if I could say “assume everything in this namespace is non-null by default except for things marked @Nullable”. I have a codebase where things (mostly return values and parameters) that can be null are marked as such, and everything else isn’t annotated.


#2

We do not support annotations from JSR 305 (which is not a standard, because it never shipped) yet, but we will eventually.

As of having default nullability for whole libraries, this makes total sense indeed, thanks for the suggestion.
