When creating a route from File Camel starts working on the file before it is fully transferred, which results in an error.

Target for 1.5. Important that Camel has good components for file, ftp etc. as they are still a major means of transport for integrations.

[Claus Ibsen]

The same could apply for the plain File component.

The same for FileConsumer, should not poll the file before it has access. Maybe a new option to set this strategy

[Claus Ibsen]

I am adding a new option - consumer.exclusiveRead with values true|false that will only start polling the file if it has exclusive read to the file (= not in progress of being written).

I am opting for a default value of true so we don't poll files in progress. Anyone thoughts on this?
I have implemented it for the regular FTP component. Will check the SFTP part later.

Comitted to trunk

The option has been renamed to: consumer.exclusiveReadLock and is default true in Camel 1.5
