Dear camel-community
I have the following route (simplified):
RemoteFileEndpoint ftpEndpoint =
endpoint("sftp:ftp.myhost.com/?username=user&password=xxxxx&delay=43200000&disconnect=true",
RemoteFileEndpoint.class);
ftpEndpoint.setFilter(new MyDownloadFileFilter());
from(ftpEndpoint)
.to("file:{{configured.dl.dir}}")
.log("Downloaded ${header.CamelFileName} over FTP")
.to("direct:further-processing")
.end();
This route worked as expected and I could download all files that are
accepted by MyDownloadFileFilter.
After upgrading from 2.15.x to the latest camel version 2.16.0, I faced the
following exception:
WARN ] 2015-11-25 09:41:12.988 [Camel (camel-1) thread #2 -

failed polling endpoint:

Will try again at next poll. Caused by:

What could be the issue here? I tried to play with the 'disconnect' and the
'stepwise' flag, but it does not resolve the issue. Thanks for your help.
