Spring Boot 3.0.1升级后Spring Integration Flow出现ClassCastException

升级完成后，原本正常运行的Spring Integration Flow抛出ClassCastException：

class org.springframework.messaging.handler.HandlerMethod$HandlerMethodParameter cannot be cast to class java.lang.reflect.Type (org.springframework.messaging.handler.HandlerMethod$HandlerMethodParameter is in unnamed module of loader 'app'; java.lang.reflect.Type is in module java.base of loader 'bootstrap')

更新： 异常源自Spring Cloud Function Context中的JsonMessageConverter，在尝试将类型为HandlerMethodParameter的conversionHint对象强制转换为Type时触发：

Cannot cast 'org.springframework.messaging.handler.HandlerMethod$HandlerMethodParameter' to 'java.lang.reflect.Type'

受影响的集成流及Transformer代码 #

集成Flow定义 #

@Bean
IntegrationFlow extract(SessionFactory<SftpClient.DirEntry> sftpSessionFactory,
                        XmlFileTransformer xmlFileTransformer){
   return IntegrationFlow
            .from(Sftp.inboundAdapter(sftpSessionFactory)
                    .preserveTimestamp(true)
                    .remoteDirectory("foo")
                    .regexFilter(".*\\.txt$")
                    .localDirectory(new File("sftp-inbound")), e -> e.id("sftpInboundAdapter")
                    .autoStartup(true)
                    .poller(Pollers.fixedDelay(5000))
            )
            .log(LoggingHandler.Level.DEBUG, "ExtractFlow", m -> "Successfully reached")
            .wireTap(MONITORING_FLOW)
            .log(LoggingHandler.Level.DEBUG, "ExtractFlow", m -> "Successfully done wire tap")
            .transform(xmlFileTransformer)
            .log(LoggingHandler.Level.DEBUG, "ExtractFlow", m -> "Successfully done transformation")
            .handle(m -> xmlProcessor.process((XmlFile) m.getPayload())
            .get();
}

XmlFileTransformer实现 #

@RequiredArgsConstructor
@Component
public class XmlFileTransformer implements GenericTransformer<Message<File>, XmlFile> {
   @Override
   public XmlFile transform(Message<File> message) {
       return new XmlFile(message.getPayload().toPath(), message.getHeaders().get("x-origin", String.class));
   }
}

wiretap对应的集成流同样通过实现GenericTransformer进行转换（写法与XmlFileTransformer类似），随后使用Amqp.outboundAdapter发送消息。

xmlProcessor.process方法接收XmlFile作为参数，但该方法从未被执行——异常在尝试通过wiretap时就会触发；若注释wiretap，则在执行xmlFileTransformer转换时触发异常。日志消息"Successfully reached"输出后立即出现异常。

已反复检查依赖，确保没有新旧版本冲突，大部分依赖使用spring-boot-starter-parent提供的版本。对照Spring Integration 6.0.0迁移指南，未发现遗漏的重大变更，也未找到类似的升级案例。

请问这是Spring Integration的Bug吗？还是需要重构代码适配Spring Integration 6.0？或是我忽略了某些依赖问题？
