> Current code in {{Evaluators.java}} is
> {noformat}
>     for (final EvaluatorManager evaluatorManager : evaluatorsCopy) {
>       LOG.log(Level.WARNING, "Unclean shutdown of evaluator {0}", evaluatorManager.getId());
>       if (!evaluatorManager.isClosedOrClosing()) {
>         evaluatorManager.close();
>       }
>     }
> {noformat}
> The warning about unclean shutdown is posted even for evaluators which are already closed or closing. We should move the log inside {{if}} statement, so that it is written only if action is taken to close the evaluator forcefully.
