I have installed proto3 from yesterday's master and it all seems to work
fine. Also managed to get it to work with python without too much trouble.
I am running on Windows.
I am now following the instructions in protobuf/java, though, and am
running into the following error:
C:\coding\proto\protobuf\java>mvn test

(and then a lot more similar failures).
Has anyone seen that before? A quick look around (stackoverflow etc) did
not come up with any hits, but I apologise in advance if this was a
well-known problem that I could have easily fixed myself.
Thanks,
