I added a commit to manage the version of org.reactivestreams:reactive-streams, as the BOM no longer does this. I filed reactor/reactor#768 to ask for a release notes entry or revert.

The build won't pass yet, as I'll need to address some NullAway warnings due to the new JSpecify support.

[NullAway] returning @nullable expression from method with @nonnull return type

Line 1216 in cf25141

return flux.map(v -> transformation(v)).mapNotNull(o -> o.orElse(null));

@msridhar perhaps I'm overlooking something trivial, but I'm not sure how to resolve this warning and the two similar ones shown below. Now that Project Reactor adopted JSpecify, the signature of Flux#mapNotNull is:

public final <V> Flux<V> mapNotNull(Function <? super T, ? extends @Nullable V> mapper)

The use of .orElse(null) here seems compatible with that. Note that the warning is reported on the whole o -> o.orElse(null) lambda expression.

[msridhar]

I think this might get resolved by uber/NullAway#1337 (FYI @dhruv-agr). We will try testing on our end and let you know. If you need to merge this in the meantime, I think you'll have to suppress.

[Stephan202]

Tnx for the quick response; clear! 💪
