Native gRPC application: missing method "valueOf" #24510
Comments
|
Additional information: I found that the problem did not occur if I annotated the inner enum class with public final class LanguageSpec
extends com.google.protobuf.GeneratedMessageV3
implements LanguageSpecOrBuilder {
...
@RegisterForReflection // <=== added this ===
public enum Language
implements com.google.protobuf.ProtocolMessageEnum {
ENGLISH(0),
FRENCH(1),
SPANISH(2),
UNRECOGNIZED(-1),
;
public static final int ENGLISH_VALUE = 0;
public static final int FRENCH_VALUE = 1;
public static final int SPANISH_VALUE = 2;
public final int getNumber() {
if (this == UNRECOGNIZED) {
throw new java.lang.IllegalArgumentException(
"Can't get the number of an unknown enum value.");
}
return value;
}
@java.lang.Deprecated
public static Language valueOf(int value) {
return forNumber(value);
}
public static Language forNumber(int value) {
switch (value) {
case 0: return ENGLISH;
case 1: return FRENCH;
case 2: return SPANISH;
default: return null;
}
}

Since the gRPC code is generated and should not be modified, I tried registering the problematic inner class using another class, it is did successfully work-around the missing method problem: package net.example;
import io.quarkus.runtime.annotations.RegisterForReflection;
import net.example.grpctest.LanguageSpec;
@RegisterForReflection(targets = { LanguageSpec.Language.class })
public class GrpcInnerClassWorkAround {
} |

The issue is that we do not register the enum class. It should be done automatically. |
Protobuf enums generate enum classes. Fortunately, we can locate them with Jandex using the ProtocolMessageEnum interface, as the generated enums implement this interface. Fix quarkusio#24510.

Reproduced on dependencies in owned generated enum protobuf-maven-plugin is it possible somehow to solve the problem without reflection-config.json |

Describe the bug
I am seeing an issue when I have a gRPC message with an inner-enum. If I run the application in dev mode or from a JAR, all is fine, but when I build and run as a native app, an exception is thrown complaining that the valueOffor the enum is missing. I have checked the generated code and the method is actually present. I did notice that the method was annotated with @deprecated (not sure if this is relevant).
This occurs with both the gRPC server application and gRPC client application.
Expected behavior
Should run without any complaints.
Actual behavior
