Answer 1

Did you implement the filters in your web.xml?

 <filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>-->
    <filter-mapping>
        <filter-name>springSecurityFilterChain</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

The issue is related to SEC-2382 and can be resolved by updating to Spring Security 3.2.0.RELEASE. For reference, you will want to update the SecurityConfig as shown below:

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private DataSource dataSource;

    @Autowired
    private UserDetailsService myCustomUserDetailsService;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .jdbcAuthentication()
                .dataSource(dataSource)
                .and()
            .userDetailsService(myCustomUserDetailsService);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/app/**").hasRole("ADMIN")
                .and()
            .formLogin()
                .loginPage("/index.jsp")
                .defaultSuccessUrl("/app/")
                .failureUrl("/index.jsp")
                .permitAll()
                .and()
            .logout()
                .logoutSuccessUrl("/index.jsp");
    }

}
