Overview
After migration to spring boot 2.2 we noticed that behavior of the annotations scan has been changed. In our case we define @SpringBootApplication in the base abstract class
@SpringBootApplication
public abstract class BaseApplication {
protected abstract BaseApplication getApp();
public void start(String[] args) {
SpringApplication.run(getApp().getClass(), args);
}
}and then multiple concrete applications extend this class
public class DemoApplication extends BaseApplication {
public static void main(String[] args) {
new DemoApplication().start(args);
}
@Override
protected BaseApplication getApp() {
return this;
}
}It works fine in the v 2.1.x, but in 2.2 attempt to run the app causes the error:"
java.lang.IllegalArgumentException: No auto-configuration attributes found. Is com.xxx.Application annotated with EnableAutoConfiguration
2019-11-13 09:52:58.571 ERROR 97155 --- [ main] o.s.boot.SpringApplication : Application run failed

Steps to reproduce
- use attached demo project to reproduce the issue
demo.zip
- change spring-boot version to 2.1.8.RELEASE and run app again - everything works as expected
