Impact of not using ROLE_ prefix in spring security framework

what is the impact here if I use the line which does not have "ROLE_" prefix in the @Secured Annotation? Assuming that the spring security RoleVoter expects roles to be prefixed with "ROLE_" .

• @Secured({"ADMIN"})


• @Secured({"ROLE_ADMIN"}) public void sampleMethod(SampleClass sampleObject) { Operations; }
