Steps to reproduce this issue

@Test
public void testGenericAsyncInvoke() throws InterruptedException, ExecutionException {
HttpServiceImpl server = new HttpServiceImpl();
Assertions.assertFalse(server.isCalled());
ProxyFactory proxyFactory = ExtensionLoader.getExtensionLoader(ProxyFactory.class).getAdaptiveExtension();
Protocol protocol = ExtensionLoader.getExtensionLoader(Protocol.class).getAdaptiveExtension();
int port = NetUtils.getAvailablePort();
URL url = URL.valueOf("http://127.0.0.1:" + port + "/" + HttpService.class.getName() + "?release=2.7.0");
Exporter<HttpService> exporter = protocol.export(proxyFactory.getInvoker(server, HttpService.class, url));
Invoker<GenericService> invoker = protocol.refer(GenericService.class, url);
GenericService client = proxyFactory.getProxy(invoker, true);
CompletableFuture future = client.$invokeAsync("sayHello", new String[]{"java.lang.String"}, new Object[]{"haha"});
Assertions.assertTrue(server.isCalled());
Assertions.assertEquals("Hello, haha", future.get());
invoker.destroy();
exporter.unexport();
}

Issue 2:
[ ☑️] I have searched the issues of this repository and believe that this is not a duplicate.

[ ☑️] I have checked the FAQ of this repository and believe that this is not a duplicate.

Environment

Dubbo version: 2.7.3~2.7.5

Operating System version: MacOS

Java version: 1.8

Steps to reproduce this issue

工程分4个子模块 api、common、consumer、provider

自定义异常、状态码定义在common模块

定义了两类自定义异常，一个BaseException直接继承RuntimeException；一个BaseRpcException继承RpcException。

具体查看以下提供的示例工程

Pls. provide [GitHub address] to reproduce this issue.

https://github.com/mbc3320/dubbo-demo-custom-exception.git

Expected Result

consumer端能正常序列化自定义异常并正确抛出

What do you expected from the above steps？

Actual Result

provider端抛出DemoException、DemoRpcException自定义异常，consumer端俘获并处理异常，测试了4种方式，都存在不同程度的问题

（1）继承BaseException的异常，方法不签名抛出异常类型，consumer端会直接序列化为RuntimeException，consumer只会调用一次Provider

（2）继承BaseException的异常，方法签名抛出BaseException，会序列化为RuntimeException，consumer只会调用一次Provider

（3）继承BaseException的异常，方法签名抛出DemoException，报空指针且序列化失败，consumer会调用三次Provider

（4）继承BaseRpcException的异常，方法不签名抛出异常类型，报空指针且序列化失败，consumer会调用三次Provider

（5）如果dubbo.provider.filter设置了-exception，则所有以上情况，结果都会跟（4）一样，报空指针且序列化失败，consumer会调用三次Provider

What actually happens?

If there is an exception, please attach the exception trace:
