No, there must be a problem with the script, because ctx and vars are
created as follows by the BeanShell PostProcessor:
JMeterContext jmctx = JMeterContextService.getContext();
JMeterVariables vars = jmctx.getVariables();
bshInterpreter.set("ctx", jmctx);
bshInterpreter.set("vars", vars);
If you re-read the posted script, you should see that if rand >= 40 (
i.e. approx 60% of the time) then the final vars.put will set somelist
to null.
