Error Prone VS manifold

error-prone is good for some extra static analysis.

A special kind of validation is enforcing that record fields are not null. (Un)fortunately, records do not have any special behavior regarding nullability. You can use tools like NullAway or Error Prone to prevent null in your code in general, or you can add checks to your records:

I am all in favour to more third side libraries adding functionalities, like Lombok, Manifold and error prone. As well as smaller projects like this shameless plug and what appears in this list

If only Google didn't suck when it came to Java9+ support... https://github.com/google/error-prone/issues/2649

I haven't used it. I use Google's ErrorProne + Lombok to prevent NPEs in java.

Take a look at NullAway, a plugin for Error Prone.

For some of this stuff, there are compiler extensions that allow extra type checking to be added e.g. Google Error-Prone: https://github.com/google/error-prone with stuff like: https://errorprone.info/bugpattern/ReturnMissingNullable.

Doesn't help you with third party libraries, but across an org applying that rule (and others!) typically ensures some consistency.

How to build a static analysis plugin. Google has a framework for Java with a good tutorial.

Considering the Amount domain types, I like the manifold project’s unit expression[1] approach where the unit and domain type are integrated and always reconciled.

> I am glad to see a project that provides a robust and elegant API for building rest services in Java.

Alternatives for _consuming_ REST services is perhaps an equally interesting proposition, particularly since there are potentially potentially many consumers per service e.g., the manifold JSON project[1].

Other areas where Springboot feels overbearing include JPA/ORM support. In my view this is its greatest weakness, but like the "no one ever got fired for buying IBM" cliche, the same can be said today about Springboot.
