New issue 526 by dusan...@gmail.com: 2.5.0 - Java compilation - Find
unknown fields in ... BUG
http://code.google.com/p/protobuf/issues/detail?id=526

What steps will reproduce the problem?
- upgrade to 2.5

What is the expected output? What do you see instead?
- expected: java sources
- I see: protoc error


What version of the product are you using? On what operating system?
- 2.5.0 win32


Please provide any additional information below.

Upgrading to 2.5.0 our build stops working. Executing protoc I get:

[libprotobuf FATAL google/protobuf/compiler/java/java_file.cc:123] CHECK
failed: CollectExtensions(*dynamic_file_proto, extensions): Find unknown
fields in FileDescriptorProto when building authentication_protocol.proto.
It's likely that those fields are custom options, however, those options
cannot be recognized in the builder pool. This normally should not happen.
Please report a bug.

I can't attach our protocols directly into this issue, but I could send
them private by mail on request.

Thank you.

Can you find a minimum .proto file that can reproduce the problem and then
attach the source?

Hi,

sorry, I can't isolate the problem.

It seems to be some 'race' bug, because when I change 'protoc' argument
order ( but I still use the same bundle of .proto files ), compilation
succeed.

Please see attached ( a little bit complex ) example.

You can simulate the problem easily - see two shell scripts - one will
fail, one will succeed. It seems there is no sense in order of arguments
in 'success' script, because all higher level protocols (
authentication, system information ... ) are based/encapsulated into
lower level protocols (nano, header, ...).
