> Camel FTP endpoint cannot recover by itself after network failure if no
> custom PollingConsumerPollStrategy is defined. Few years ago there was
> similar issue (https://issues.apache.org/jira/browse/CAMEL-1838), and it was
> fixed by adding in RemoteFileConsumer:
> this.setPollStrategy(new RemoteFilePollingConsumerPollStrategy());
> However it is broken again, as FtpEndpoint is overriding it with
> DefaultPollingConsumerPollStrategy in initConsumerProperties method,
> inherited from ScheduledPollEndpoint. I believe
> RemoteFilePollingConsumerPollStrategy should be used as default in
> RemoteFileEndpoint as well.
> Adding this.setPollStrategy(new RemoteFilePollingConsumerPollStrategy()); in
> RemoteFilePollingConsumerPollStrategy should fix this issue.
> Workaround for this bug is to create RemoteFilePollingConsumerPollStrategy in
> the registry and provide it directly to FTP endpoint by adding
> consumer.pollStrategy=#myRemoteFilePollingConsumerPollStrategyBeanId to the
> URL. This is also why FromFtpSimulateNetworkIssueRecoverTest didn't catch it
> - it's using custom PollingStrategy.
