Hi Guys,

What steps will reproduce the problem?
1. Download and install 2.5.0 from here 
https://github.com/google/protobuf/releases
(./configure && make && make install)
$ protoc --version
libprotoc 2.5.0
2.Generate .java file: protoc --java_out=src/java/ 
resources/proto/realtime-bidding.proto --proto_path=resources/proto
3. lein run (it's actually clojure project and i  see 
com.google.protobuf/protobuf-java 2.5.0 on classpath)

I'm getting following error:

Exception in thread "main" java.lang.VerifyError: class 
RealtimeBidding$BidRequest overrides final method 
getUnknownFields.()Lcom/google/protobuf/UnknownFieldSet

I also saw that ticket https://code.google.com/p/protobuf/issues/detail?id=484 
but it didn't help.
RealtimeBidding.java is here

We don't have 2.5.0 on the github release page (the oldest there is 2.6.0). 
Could you check the version number again?
