The easiest explanation for this is that the slave.jar is out of sync (the Flush class in question was added in 2007, so if the slave.jar is older than that, you'll see this problem.) Then I quickly realized that you've used the ssh-slaves plugin, which always copies up-to-date slave.jar.
Then I thought maybe the problem is a failure to initialize a class, but then again I quickly realized that the root cause is ClassNotFoundException, so that can't be the case.
The system has successfully loaded RemoteOutputStream class as that's showing up in the stack trace, so it's using the right classloader, too.
So I have no clue why it's failing to find the class in question. I need to run this in the debugger and step execute into why URLClassLoader doesn't find the class in question.
