             Summary: EventDrivenPollingConsumer can lose exchanges when the internal queue is full
                 Key: CAMEL-7411
                 URL: https://issues.apache.org/jira/browse/CAMEL-7411
             Project: Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 2.13.0
            Reporter: Benedikt Waldvogel


The exchange processing in the {{EventDrivenPollingConsumer}} can lose exchanges when the internal queue is bounded and full.

The implementation:
{noformat}
public void process(Exchange exchange) throws Exception {
    queue.offer(exchange);
}
{noformat}

The reason is that {{BlockingQueue.offer(...)}} is non-blocking and returns a boolean which indicates whether the element was added.
However, the return value is ignored causing the exchange to get lost if it could not be added.

A potential workaround is to use an unbounded BlockingQueue (e.g. LinkedBlockingQueue).
