I upgraded from Jenkins 2.319 to 2.320, and all agents failed to start up. I have agents running on Linux, Mac OS, Solaris, and Windows. Below is the error I got.

The work around is to visit every agent and remove the remoting.jar from the previous start up. Without an existing remoting.jar, the agents started up just fine. However, in 2.319 and earlier, I didn't need to manually delete the old file.
