>             Project: Camel
>          Issue Type: Improvement
>          Components: camel-core, camel-ftp, camel-quartz2
>    Affects Versions: 2.13.1
>         Environment: Quartz 2.2.1 with JDBC JobStore
>            Reporter: Steffen Ryll
>            Assignee: Claus Ibsen
>             Fix For: 2.14.0, Future

> I configured a setup with an SFTP consumer like this in Spring DSL:
> {code}
> <from uri="sftp:user@host/some.directory?privateKeyUri=classpath:FOO.key&amp;delete=true&amp;scheduler=#q2scheduler"
/>
> {code}
> Note: q2scheduler refers to an instance of QuartzScheduledPollConsumerScheduler that
I set have up with my Cron pattern.
> Starting up the Camel context fails with a NotSerializableException as soon as I switch
Quartz from a RAMJobStore to a JDBCJobStore.
> The following exception gets thrown:
> {code}
> org.quartz.JobPersistenceException: Couldn't store job: Unable to serialize JobDataMap
for insertion into database because the value of property 'task' is not serializable: org.apache.camel.component.file.remote.SftpConsumer
[See nested exception: java.io.NotSerializableException: Unable to serialize JobDataMap for
insertion into database because the value of property 'task' is not serializable: org.apache.camel.component.file.remote.SftpConsumer]

> That implies, that a File consumer will fail in such a scenario as well, not only an
SFTP consumer.
> Given that the documentation http://camel.apache.org/file2.html advertises Quartz2 support
for polling scheduling, we were expecting that this really works.
> For us, this is kind of tragic, as we wanted to use Quartz2's clustering capabilities
to make the SFTP consumer fit for use in a (Weblogic) cluster.
> Looking at GenericFileConsumer, it seems at least non-trivial to make all the fields
in SftpConsumer's class hierarchy serializable.
