[Question] [Java]Serializing a ProtobufXXXXClass.Builder object may throw an exception

Question

Serializing a ProtobufXXXXClass.Builder object may throw an exception:
Exception in thread "fory-jit-compiler-56" java.lang.RuntimeException: java.lang.NoSuchMethodException: no such method: com.google.protobuf.MapEntry.parseFrom(CodedInputStream)MapEntry/invokeStatic

Analysis: Because the Builder class does not match any branch in ProtobufDispatcher, its internal fields are subsequently traversed. MapEntry indeed does not contain a parseFrom method.

Question: Should Fory support serializing the Builder class, or is it sufficient to only support the finalized object returned by Builder.build()?

No, it's not supported.

And if you are intertested, we will release fory compiler in 0.15.0, which can generate fory class from protobuf: https://fory.apache.org/docs/next/compiler/protobuf_idl_support

Such classes can be serialized by fory efficiently

Thank you, I understand. In version 0.12, the protobuf bridge layer is a temporary solution; let's keep it as it is for now.
