   I have a question about FileDescriptorSet field. In https://github.com/apache/pulsar/blob/c01b1eeda3221bdbf863bf0f3f8373e93d90adef/pulsar-client/src/test/java/org/apache/pulsar/client/impl/schema/ProtobufNativeSchemaTest.java  file there is an example test class. It is generated from Test.proto and ExternalMessage.proto files. The problem is that, no matter what I try with protoc , I can not get same FileDescriptorSet  content. It's always slightly different. I tried csharp, java, cpp output, with or without --descriptor_set_out - I always get different byte array (and base64 string). And I can not create producer/consumer on apache pulsar client with FileDescriptorSet  generated by me, I get com.google.protobuf.InvalidProtocolBufferException.invalidEndTag exception which as far as I googled tells that data is corrupted. When I try to create producer with FileDescriptorSet   data from test, it works. What am I doing wrong while generating descriptors using protoc ?
