It seems that enabling "Treat failed test cases (as indicated by JUnit/xUnit/... publishers) as failure causes." option can cause serious problems because the messages returned have not size limit.

We identified messages of over 2MB being returned which would break Gerrit integration making it it fail to post the result due to message size.

I think that BFA should cut any message to a reasonable limit (like 4Kb or so) in order to avoid breaking consumers.
