Sure, this is it
Actually it usually happens when i see the graph, go back
change a little the program and recreate the package with maven (same name for the jar)
re-upload the package and try to re-start it
killing e restarting the web-client solve the problem
An error occurred while invoking the program:
The main method caused an error.
java.io.IOException: Class not found
