I'm consuming a library that has properties annotated with @NotNull (jakarta) but not @Nullable; it also provides no package-info.java; is there a way to tell Kotlin that types without @NotNull in a package root should be treated as nullable?

[Vampire]

Did you try to annotate the package in package-info.java with @Nullable?

[Bernhard]

it's a jar from maven, can I override that locally when pulling that down as a dependency?

[Vampire]

Don't think so

If you are the owner of that Java lib I think you can add annotations for "NotNull"
https://reflectoring.io/spring-boot-null-safety-annotations/

Ubleash uses their own in https://github.com/Unleash/unleash-client-java/blob/main/src/main/java/io/getunleash/package-info.java#L1

[Bernhard]

unfortunately I'm not

[Johan]

I think I read it all wrong.
I would have guessed that the values/values returned by Java code to be nullable if not defined otherwise?

[Bernhard]

at least how I kinda understood it by now: you need to annotate the package for that to work

[Bernhard]

I think there are annotations on how nullability is decided if an annotation is absent

Without annotation they are potentially nullable, they are so-called platform types, the ones with ! suffix in the IDE type display.
