title: Springboot 2.3.x application stuck on startup
body: <p>I have a standard spring boot application with the following spring auto configuration</p>
  
  <pre><code>    implementation 'org.springframework.boot:spring-boot-starter-actuator'
      implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
      implementation 'org.springframework.boot:spring-boot-starter-web'
      implementation 'org.springframework.boot:spring-boot-starter-validation'
  </code></pre>
  
  <p>The app runs fine until I create my first entity and repository and service referencing them: </p>
  
  <pre><code>@Entity
  @Table(name = "xxx")
  public class XXX extends AuditingEntity{
  
  
  @Repository
  public interface XXXRepository extends CrudRepository&lt;XXX, Integer&gt; {
  
  }
  
  @Service
  public class XXXService {
  
      @Resource
      XXXRepository xxxRepository;
      ...
  
  </code></pre>
  
  <p>The application just failed to start and stuck on the following and never preceding</p>
