In place? Without the servlet container running? As documented?

That seems impossible to me given that it's referencing a system file on the file system that doesn't even exist anymore if you had upgraded in place. That system file content is out of date and will not work, and is referencing old classes that don't exist.

An upgrade to 4.1 will leave essentially nothing left in system/ except a few stubbed files for compatibility with the older web.xml file. It removes and replaces them. You have to have deliberately subverted the upgrade process in some way to prevent it from dealing with those files.

Your problem is related to the fact that those system files have been put back after the upgrade completed. You can't "fix" it from there, you need to start over from the beginning and upgrade again, but whatever you did that caused that is what needs to be prevented.
