This was a hypothetical, hopefully plausible, possibility that reproduced the actual error. I don’t work on the JDK and don’t know how I would debug to get the values actually being passed. Possibly a ‘debug’ option where the script output is saved instead of being written to a temporary file and disappearing could be useful?
