If think you are misusing the API. The sample code does not really say what 
does your code actually look like, it doesn't look like you are using the API 
in a correct way.

However I would recommend you to first prepare all the stubbing before passing 
mocks to different threads.

Also you should have asked us on the mailing list, instead of reporting a bug 
here.

Take a look at the FAQ. Stubbing or verifying concurrently does not make sense 
because it always lead to random results. Also, the mockito API cannot 
guarantee thread safety for stubbing and verification because of they way the 
DSL is designed.

As Brice mentions: feel free to use mocks concurrently, however prepare (stub) 
them *before* the concurrency starts.

Hope that helps!
