Exception with teamAccept & teamFetch in build using M3a

While on M2, my build definition worked beautifully producing a build. Since we upgraded our server to M3a, my bootstrap.xml file that does a teamAccept and a teamFetch, gets an exception in both cases (teamFetch after I have commented out teamAccept). Following is the stack trace. Any ideas as to what its trying to tell me?
