Exception is thrown when using this example: https://github.com/Pi4J/pi4j-jbang/blob/main/Pi4JPWMLed.java It works, but throws an exception in the beginning:

@FDelporte /sys/module/spidev/parameters looks like the install of spiDev loads this file. It is used in Pigpio init code. The local variable was already set to 4069 so the exception is no problem. The fact they wrote the code this way makes me think they believed this could happen. I don't have a clean SD card to start different ways to load it and download and then use the jbang examples to see if I can replicate. Do you remember how you setup the Pi you used ? and how you ran the pgm, remote/on the Pi etc ?
