Answer 2

Según el javadoc of NotEmpty, Integer no es un tipo válido para que se compruebe. Es para cadenas y colecciones. Si solo quiere asegurarse de que un entero tenga algún valor, javax.validation.constraints.NotNull es todo lo que necesita.

public @interface NotEmpty

Asserts that the annotated string, collection, map or array is not null or empty.
