Which @NotNull Java annotation should I use?

Question

I\'m looking to make my code more readable as well as use tooling like IDE code inspection and/or static code analysis (FindBugs and Sonar) to avoid NullPointerExceptions.

Answer 1

Unfortunately, JSR 308 will not add more values than this project local Not Null suggestion here

Java 8 will not come with a single default annotation or its own Checker framework. Similar to Find-bugs or JSR 305, this JSR is poorly maintained by a small bunch of mostly academic teams.

No commercial power behind it, thus JSR 308 launches EDR 3 (Early Draft Review at JCP) NOW, while Java 8 is supposed to ship in less than 6 months:-O Similar to 310 btw. but unlike 308 Oracle has taken charge of that now away from its founders to minimize harm it'll do to the Java Platform.

Every project, vendor and academic class like the ones behind the Checker Framework and JSR 308 will create its own proprietary checker annotation.

Making source code incompatible for years to come, until a few popular compromises could be found and maybe added to Java 9 or 10, or via frameworks like Apache Commons or Google Guava;-)
