You are using a field with a too large field number. The generated Java
code should compile fine if the field number is smaller than 2<<28.

[protobuf] Java classes generated from .proto file don't compile

2016-09-23 Thread Denis Vlah 
Hello everyone.

I have the following problem:
The Java classes generated from .proto file doesn't compile.

The original .proto file was generated from C# protobuf-net classes.

There is a big switch in the generated javacode:


 public  static final class Object extends
  com.google.protobuf.GeneratedMessageV3 implements
  // 
@@protoc_insertion_point(message_implements:Forcive.Dto.Objects.Object)
  ObjectOrBuilder {
// Use Object.newBuilder() to construct.
private Object(com.google.protobuf.GeneratedMessageV3.Builder 
builder) {
  super(builder);
}
private Object() {
}

@java.lang.Override
public final com.google.protobuf.UnknownFieldSet
getUnknownFields() {
  return this.unknownFields;
}
private Object(
com.google.protobuf.CodedInputStream input,
com.google.protobuf.ExtensionRegistryLite extensionRegistry)
throws com.google.protobuf.InvalidProtocolBufferException {
  this();
  int mutable_bitField0_ = 0;
  int mutable_bitField1_ = 0;
  int mutable_bitField2_ = 0;
  int mutable_bitField3_ = 0;
  com.google.protobuf.UnknownFieldSet.Builder unknownFields =
  com.google.protobuf.UnknownFieldSet.newBuilder();
  try {
boolean done = false;
while (!done) {
  int tag = input.readTag();
  switch (tag) {
 case 2171691026: {
  Forcive.Dto.Objects.AllMessages.UserDto.Builder subBuilder = 
null;
  if (((bitField1_ & 0x8000) == 0x8000)) {
subBuilder = userDto_.toBuilder();
  }
  userDto_ = 
input.readMessage(Forcive.Dto.Objects.AllMessages.UserDto.PARSER, 
extensionRegistry);
  if (subBuilder != null) {
subBuilder.mergeFrom(userDto_);
userDto_ = subBuilder.buildPartial();
  }
  bitField1_ |= 0x8000;
  break;
}



The Java error is Error:(78413, 18) java: integer number too large: 
2171691026

The C++ generated classes from the same .proto file compiles fine.

Any ideas how to fix this?

Thanks
