In my Eclipse Neon workspace settings i checked [x] Enable annotation-based null analysis. Now when I'm doing Assign statement to new variable from quick assist, Eclipse sometimes adds @NonNull to the new variable assigment. So intead of line 1, I get line 2: Deprecated a = Main.class.getAnnotation(Deprecated.class); // line 1 @NonNull Deprecated a = Main.class.getAnnotation(Deprecated.class); // line 2 This raises two questions: 1. How can I enable and disable this behaviour? In a second project within the same workspace Eclipse doesn't to this. So it doesn't only depend on the annotation-based null analysis which was configured in the workspace settings. 2. Why does Eclipse conclude annotation is @NonNull while the return value can be clearly be null (by documentation): Annotation Class.getAnnotation(java.lang.Class annotationClass) Returns this element's annotation for the specified type if such an annotation is present, else null.
