This affects 6.1.x and later. Here's a minimal Boot app that should illustrate the problem:
package com.example.gh_37101;
import java.util.ArrayList;
import java.util.List;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.SpringBootConfiguration;
import org.springframework.context.annotation.Bean;
import org.springframework.validation.annotation.Validated;
import org.springframework.validation.beanvalidation.BeanValidationPostProcessor;
import com.example.gh_37101.Gh37101Application.Example.Exclude;
import jakarta.validation.Valid;
import jakarta.validation.constraints.Pattern;
@SpringBootConfiguration
public class Gh37101Application {
@Bean
static BeanValidationPostProcessor beanValidationPostProcess() {
return new BeanValidationPostProcessor();
}
@Bean
Example example() {
Exclude exclude = new Exclude();
exclude.setHttpStatus(List.of("invalid"));
Example example = new Example();
example.setExclude(List.of(exclude));
return example;
}
public static void main(String[] args) {
SpringApplication.run(Gh37101Application.class, args);
}
@Validated
class Example {
@Valid
private List<Exclude> exclude = new ArrayList<>();
public List<Exclude> getExclude() {
return exclude;
}
public void setExclude(List<Exclude> exclude) {
this.exclude = exclude;
}
public static class Exclude {
private List<@Pattern(regexp="^([1-5][x|X]{2}|[1-5][0-9]{2})\\$") String> httpStatus;
public List<String> getHttpStatus() {
return httpStatus;
}
public void setHttpStatus(List<String> httpStatus) {
this.httpStatus = httpStatus;
}
}
}
}
Running it on the JVM will result in a start up failure as the validation fails:

Running as a native image succeeds because AOT processing does not generate any metadata for the @Pattern container element constraint. It's missed both because the cascade on exclude isn't considered and because container element constraints are not considered.
Comment From: wilkinsona
Thanks for this, @sdeleuze. Given that you consider this to be an enhancement, am I right to assume that it won't be backported to 6.1.x?
Comment From: sdeleuze
Yeah, the change is more involved than expected, so I chose to make it 6.2+ only after discussing with the team.
