Spring Boot 3.2.0 Native构建无法启用Virtual Threads问题咨询

我在开发一个简单Web应用，希望同时利用Native编译和Virtual Threads特性。使用Spring Boot 3.2.0时，单独构建Native可执行文件或启用Virtual Threads都能正常工作，但无法同时实现两者。

唯一的Java类 #

package com.example.demo;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class DemoApplication {
    private final static Logger logger = LoggerFactory.getLogger(DemoApplication.class);

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @GetMapping("/greeting")
    public String greet() {
        logger.info("Inside greeting");
        return "Hi!";
    }
}

编译命令 #

mvn clean -Pnative native:compile

现象与疑问 #

• JVM模式下：
  • 不启用Virtual Threads时，访问接口的日志线程名为nio-8080-exec-3；
  • 启用Virtual Threads后，线程名变为omcat-handler-0，且压测后Micrometer指标jvm_threads_peak_threads会下降。
• Native编译后：
  • 无论是否启用Virtual Threads，日志线程名都为nio-8080-exec-3；
  • 压测后jvm_threads_peak_threads指标无变化。

请问这是Spring Boot/GraalVM不支持的场景，还是我操作有误？
