bug-9158

this project demonsrates Spring Security Bug #9158

Security configuration adds filter granting user with ADMIN role, role hierarchy with ROLE_ADMIN > ROLE_USER and three endpoints showing that:

• /admin mapped with @Secured works for granted ADMIN role
• /user mapped with @Secured DOES NOT work for USER role granted via hierarchy
• /userPre mapped with @PreAuth with spel hasRole(USER) works as supposed via hierarchy

probably just exchanging RoleVoter with RoleHierarchyVoter will do the trick, but I'm not sure what about regression
