@Kai
hi the latest changes from ESH bumped xtext to 2.9.2

some of my rule do throw now:
Exception in thread “Alarm bei Node 18” java.lang.NullPointerException
at org.eclipse.smarthome.model.script.engine.ScriptExecutionThread.run(ScriptExecutionThread.java:44)

example rules with exception since 2.9.2

rule "Alarm bei Node 18"
when
	Item zwave_device_15348538564_node18_sensor_binary changed to ON
then
	var String MotionLocation
	
	MO1_Motion_LastMovement.postUpdate (	new DateTimeType().format("%1$td.%1$tm. %1$tH:%1$tM") ) /
	MO1_Motion_LastMovement.persist
	MotionLocation = "Flur"

	General_Motion_LastMovement.postUpdate (	new DateTimeType().format("%1$td.%1$tm. %1$tH:%1$tM") + " (" + MotionLocation + ")" )  
	General_Motion_LastMovement.persist
		logInfo("Motion", "Bewegung an MO1 registriert um "+ MO1_Motion_LastMovement)
end

Can you add an issue at ESH? Best with an easily reproducible use case based on the demo items.
