Re: @Nonnull?
I've just been informed that @Nonnull could be part of javax (the documentation does appear to state this). I don't think I have access to this package because I'm not using anything other than the Java SE API.
Re: @Nonnull?
I commonly generate custom runtime exceptions for situations like this, but
it perhaps would be nice to have the compiler flag where this situation is
likely to happen too.
Perhaps it is a feature of a later release...

Re: @Nonnull?
Yes, googled a bit for this, doubt it exists as a feature in JDK 16.

Re: @Nonnull?
What @Nonnull in Java ? Have I missed some news about a new feature
in the JDK?
Various third party libraries implement some form of non-null
annotation and you will have to use one such library ... unless I
missed some new JDK feature. :-)
