spring-boot spring-security java Java

Does anyone know how to I'm working with an `IllegalStateException` when trying to call a method secured with `@PreAuthorize` in my Spring Boot application. The method in question is annotated like this: ```java @PreAuthorize("hasRole('ADMIN')") public void performAdminTask() { // Some admin task } ``` When I try to call `performAdminTask()` from a service class, I get the following stack trace: ``` java.lang.IllegalStateException: Failed to introspect annotations on class ... ``` I checked the Spring Security configuration and it appears to be set up correctly. I'm using Spring Boot version 2.5.4 and Spring Security version 5.5.1. I also have the following configuration in place: ```java @EnableGlobalMethodSecurity(prePostEnabled = true) @Configuration public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .anyRequest().authenticated() .and() .formLogin(); } } ``` I've double-checked that my user has the `ADMIN` role assigned, and I can confirm that the role is being correctly applied in the database. However, the method is never reached, and I always face this `IllegalStateException`. I also tried cleaning and rebuilding the project, as well as checking for any potential issues with bean creation, but nothing seems to work. Any insights on what might be going wrong or how to better debug the scenario would be greatly appreciated. I recently upgraded to Java LTS.
