chickenlj opened a new issue, #13496:
URL: https://github.com/apache/dubbo/issues/13496
Dubbo version: 3.3.0-beta.1
When `package` and `java_package` are different in .proto
```protobuf
syntax = "proto3";
option java_multiple_files = true;
option java_package = "org.apache.dubbo.springboot.demo.idl";
package greet;
message GreeterRequest {
string name = 1;
}
message GreeterReply {
string message = 1;
}
service Greeter{
rpc greet(GreeterRequest) returns (GreeterReply);
}
```
Got the following
```java
java.lang.NullPointerException: Cannot invoke
"java.lang.reflect.Method.getGenericReturnType()" because the return value of
"org.apache.dubbo.rpc.model.MethodDescriptor.getMethod()" is null
