freegaga opened a new issue, #10165:
URL: https://github.com/apache/dubbo/issues/10165
### Environment
* Dubbo version: 2.7.12
* Operating System version: windos10
* Java version: 1.8
### Steps to reproduce this issue
ReferenceConfig<GenericService> reference = new ReferenceConfig();
reference.setInterface("com.**.**.**");
reference.setGroup(group);
reference.setVersion(version);
reference.setRetries(retryTime);
RpcContext.getContext().setAttachment("generic", "gson");
reference.setGeneric(true);
reference.setCheck(false);
reference.setTimeout(100000);
GenericService genericService =
ReferenceConfigCache.getCache().get(reference);
Map<String, Object> result = (Map<String, Object>)
genericService.$invoke(method, new String[]{param.getClass().getName()}, new
Object[]{JSONObject.toJSONString(param)});
上面是泛化调用代码
1，系统启动第一次通过泛化调用dubbo服务会报如下错误，但是第二次调dubbo服务就正常了。
2，我尝试过在调用dubbo服务的地方发生异常时捕获异常在重试也不行
Pls. provide [GitHub address] to reproduce this issue.
### Expected Behavior
If there is an exception, please attach the exception trace:
```
org.springframework.web.util.NestedServletException: Request processing
