Hi, @mp911de!

Could I work on this issue or maybe a part of it? From what I understand, the task is about replacing @nullable and @nonnull annotations with JSpecify annotations, e.g., ensuring that the necessary imports are in place where they are currently used. Is there anything else I should know before I start working on this?

Thanks!

Hey @ivamly. There's quite a bit more attached to this task. JSpecify annotations relate to the type level while Spring's @Nullable is targeting parameters, fields, and methods. Also, we're looking to leverage @Contract and integrate with NullAway.

I highly suggest waiting until common infrastructure and dependency management in the build infrastructure is in place (see spring-projects/spring-data-commons#3170). If you give this topic another month or two, then you should have everything in place to start with the task on the module level.

Thanks! I’ll wait for that.
