Hibernate @NotEmpty annotation equivalent in Javax.package or alternative

NotEmpty is just a combination of @NotNull and @Size(min=1).

Please be aware that @NotEmpty will return valid for a List<> containing a null element.

Kind of bizarre in the case of a @QueryParam List<>

As say Affe, I did a custom annotation, itself annotated with @NotNull and @Size(min=1) with a custom validator that iterates the collection and positions a boolean flag only if the elements are not null.
