Bill - I was using jconsole in both cases as that's what I nearly always use. (If you remember, I posted about some self-inflicted problems using OLE a couple of weeks ago because I forgot it only works under j.exe.) Also, my console is always running in an emacs window, if that makes a difference.
Actually, the anomalous behavior of sending output back to the parent is handy in the initial phase of development as it makes it easier to see the simple, immediate errors I encounter when I'm first developing a forked process. It would be nice to keep this behavior but to have a way to turn it off once preliminary debugging is done. I'll do some experiments to see if it persists once the process is running or if it stops happening after the initial load. You're probably right about the jprofile difference - I'll check it later. I guess this is a difference between the GUI and console version as well - j.exe loads the profile unless it's explicitly dis-allowed?
