Some things I know about are the JSENT SCADA platform http://www.jsent.co.za/, 
and Eurotech (was Arcom Control Systems) http://eurotech.com that has a 
relationship with IBM through their joint development of MQTT and other things 
uses J9 on some of their devices and is moving some of their stuff out of 
ISaGRAF toward more Java based stuff.
