Failed to execute velocity JSR233 script in JMeter

[Jmeter Tea <jm...@gmail.com>]

I Failed to execute velocity JSR233 script in JMeter,

I added velocity-engine-core-2.0.jar and
velocity-engine-scripting-2.0.jar which
include velocity in JSR223 languages list,

(Tried also with latest velocity 2.1 versions
<http://velocity.apache.org/download.cgi#engine>)

The problem that any text given is ignored, even if I put invalid syntax it
doesn't throw any exception (as in other languages), or use vars, log,...

It seems that script isn't executed,  do I need to add configurations or
jars? Or is there some JMeter/Java restrictions for velocity?

JMeter library contains velocity dependencies jars slf4j-api-1.7.25.jar
commons-lang3-3.8.1.jar and added slf4j-simple-1.7.25.jar
