I'm using latest JMeter 4 and trying to use basic jexl syntax of declaring local variable in jexl function
Local variables Can be defined using the var keyword; their identifying rules are the same as contextual variables. Basic declaration: var x;
So in JMeter I tried
${__jexl2(var x;)}
and succeeded, but using ${__jexl3(var x;)} it throw an parser exception:

Is it a JMeter issue or jexl3 issue, or am I missing something?
EDIT
In addition to failure to parse var, it can't parse ;, here's a working example with jexl2 that failed with jexl3:
${__jexl3(abc=new("java.util.ArrayList"\, 1);)}
It was a bug in JMeter Jexl3 implementation according to jexl issue:
JMeter using JexlExpression instead of JexlScript
Bug is fixed now and will be uploaded next version
