I'm seeing the generated code having in a `static` init block:
```
com.google.protobuf.Descriptors.FileDescriptor
.internalBuildGeneratedFileFrom(descriptorData,
new com.google.protobuf.Descriptors.FileDescriptor[] {
com.example.proto.options.api_docs.ApiDocsOptionsProto.getDescriptor(),
com.example.proto.options.ServerOptionsProto.getDescriptor(),
}, assigner);
com.google.protobuf.ExtensionRegistry registry =
com.google.protobuf.ExtensionRegistry.newInstance();
registry.add(com.example.proto.options.ServerOptionsProto.server);
com.google.protobuf.Descriptors.FileDescriptor
.internalUpdateFileDescriptor(descriptor, registry);
com.example.proto.options.api_docs.ApiDocsOptionsProto.getDescriptor();
com.example.proto.options.ServerOptionsProto.getDescriptor();
```
