JSR223/Groovy “unable to resolve class org.openhab.binding.mqtt.internal.action.MQTTActions” with 4.3.0.M2

[dilyanpalauzov]

With OH 4.2.2 this automation/jsr223/z.groovy file

var org.slf4j.Logger logger = org.slf4j.LoggerFactory.getLogger("org.openhab.core.model.script.rele1")
var mqtt_broker = actions.get("mqtt", "mqtt:broker:b1")

logger.info('A')
logger.info(mqtt_broker.toString())

does work and prints:

With OH 4.3.0.M2 it logs

I do not know, if this is problem in JSR223/Automation or with Groovy.
