[Bug] In the Dubbo interface, the parameter type is defined as the parent class, but when the caller invokes the remote interface method, a subclass is passed as the parameter. This leads to an inability to deserialize the parameter

Apache Dubbo Component

Java SDK (apache/dubbo)

Dubbo Version

dubbo 3.2.7 jdk 17

Steps to reproduce this issue

first:
First, i define an interface as follows:
public interface RemotePrinterService {

/**

• print file
• @param printPara
  */
  Boolean printPdfFile(PrintPara printPara);
  }

Second, create a Dubbo implementation class to implement this interface.
@DubboService
public class RemotePrinterServiceImpl implements RemotePrinterService {

private final IPrinterService printerService;

public RemotePrinterServiceImpl(IPrinterService printerService) {
this.printerService = printerService;
}

/**

• print file
• @param printPara
  */
  @OverRide
  public Boolean printPdfFile(PrintPara printPara ) {
  return printerService.printPdfFile(printPara);
  }
  }

Final, there is a service that will call this print interface. However, it added a class that extends PrintPara, and during the call, it passes a subclass of PrintPara as the parameter. This will cause the following error:
