Not sure if it's related to Apple silicone or Sonoma. Seems like javaws just doesn't work. I've installed OpenWebStart and it seems to start Finder and shows my units but crashes opening A/C.

It runs fine on Sonoma with an M1 chip.

 I've had to hunt down JRE 8 and it works now. Not sure why newer JDKs 22 do not work with javaws. Last time I've programmed in Java, 7 was just coming out. 😳
