- * <b>NOTE:</b>
- * This class is here as a TEMPORARY FIX in order to force
- * <code>@ConditionalOnClass(GlobalAuthenticationConfigurerAdapter.class)</code> in
- * <code>org.springframework.boot.autoconfigure.security.SecurityAutoConfiguration</code>.
- * <p>
- * Spring Boot M5 expects GlobalAuthenticationConfigurerAdapter to be located in package
- * <code>org.springframework.security.config.annotation.authentication.configurers</code>.
- * However, it's recently been moved to
- * <code>org.springframework.security.config.annotation.authentication.configuration</code>
- * resulting in <code>SecurityAutoConfiguration</code> <b>NOT</b> being triggered.
- * <p>
- * This class should be removed after a fix has been applied to Spring Boot M6 or RC1.
