Summary: Enabling grinder.debug.singleprocess = true breaks my script

Initial Comment:
I have a script that currently works, and wanted to enable singleprocess because I'm getting _no_ errors when things run by workers fail for some reason. However, just enabling singleprocess makes the script exit early with the following error:

Why should setting single process change anything?

this worked:

java -cp /Users/wakko/jython2.5.2/jython.jar:lib/*
-javaagent:lib/grinder-dcr-agent-3.7.1.jar net.grinder.Grinder
grinder.properties 

thank you

You probably have no instrumenters. The Grinder log file will tell you
that.

NB, if you are relying on the DCR instrumenter (e.g. you are using Jython
2.5), you need to modify the command line when starting the agent. This is
documented under grinder.debug.singleprocess at
http://grinder.sourceforge.net/g3/properties.html
