Weather concat rule... Mistake

Add-ons Bindings
#1

Everything seemed to work in openhab1 but now is broken
With the following error

2016-06-21 22:10:25.880 [ERROR] [.script.engine.ScriptExecutionThread] - Error during the execution of rule 'Weather Concat': Script interpreter couldn't be obtain

Have the following items

String		weather_temp_cond		"Today" 		(g_Weather)
Number	forecast_temp		"Temperature [%.2f °C]"			(g_Weather)	{weather="locationId=forio, forecast=0, type=temperature, property=max"}
String	weather_condition	"Условия сейчас [%s]"		(g_Weather)	{weather="locationId=home, type=condition, property=text"}

Ande the rule

rule "Weather Concat"
when
Item forecast_temp received update or
Item weather_condition received update
then
weather_temp_cond.postUpdate(forecast_temp.state.toString + " on " + weather_condition.state.toString)
end

Known issue, see https://github.com/openhab/openhab-distro/issues/191.

But we haven’t yet found a reproducible scenario. If you have one, this would be terrific. Please enter an issue for ESH as discussed here. Thanks!

Is there an option to change the rule somehow to avoid this bug?
As i have these rules as well throwing out the same error

rule "sense_kitch"
when
Item sense_kitch_temp received update or
Item sense_kitch_humi received update
then
var Number Humi_kitch = sense_kitch_humi.state
var Number Temp_kitch = sense_kitch_temp.state
var Number Humi_kitch_r = (Math::round(Humi_kitch.floatValue))
var Number Temp_kitch_r = (Math::round(Temp_kitch.floatValue))
postUpdate(sense_kitch, Temp_kitch_r + " °C  " + Humi_kitch_r + " %")
end
rule "sense_bigro"
when
Item sense_bigro_temp received update or
Item sense_bigro_humi received update
then
var Number Humi_bigro = sense_bigro_humi.state
var Number Temp_bigro = sense_bigro_temp.state
var Number Humi_bigro_r = (Math::round(Humi_bigro.floatValue))
var Number Temp_bigro_r = (Math::round(Temp_bigro.floatValue))
postUpdate(sense_bigro, Temp_bigro_r + " °C  " + Humi_bigro_r + " %")
end

Not sure if it helps but well at least i tried…

I have rewritten the rules for sense kitch and removing the special character before C at least got it updating but the same error is in the log.

rule "sense_kitch" 
when
Item sense_kitch_temp received update or
Item sense_kitch_humi received update
then
var Number Humi_kitch = sense_kitch_humi.state
var Number Temp_kitch = sense_kitch_temp.state
var Number Humi_kitch_r = (Math::round(Humi_kitch.floatValue))
var Number Temp_kitch_r = (Math::round(Temp_kitch.floatValue))
sense_kitch.postUpdate(Temp_kitch_r + "C" + Humi_kitch_r + "%")
end

Ok this is getting out of hands. i get an error

Error during the execution of rule 'Sun is shining': Script interpreter couldn't be obtain

even on this rule

rule "Sun is shining"
when Item astro_sun_elevation received update
then
if (astro_sun_elevation.state >= 0)
	{
	if (openhab_day == OFF)
		{
		openhab_day.sendCommand(ON)
		}
	}
else
	{
	openhab_day.sendCommand(OFF)
	}
end

Strangely enough - i had errors of “Script interpreter couldn’t be obtain” almost on all of my rules. They worked - but the errors were ther in the log.
After Java update from b65 (got it from debian repo) to b101 (through the java installer) i do not see any errors in the log anymore
