Camel: How to break polling on pollEnrich() when an error is thrown from poll() method

PollingConsumerStrategy.java

 public boolean rollback(Consumer consumer, Endpoint endpoint,
                            int retryCounter, Exception e)
        throws Exception
    {
        if (retryCounter < 3) {
            Thread.sleep(500);
            return true;
        }

        Exchange ex = endpoint.createExchange();
        ex.getIn().setBody(null);
        ((DefaultConsumer) consumer).getProcessor().process(ex);
        return false;
    }
