Description of problem:
There's a bug in the Camel 2.4.0 that's distributed with SOA 5.3.0. The SFTP module can't fetch files from an absolute directory.

The issue has been discussed in the Camel mailing-list, eg. http://mail-archives.apache.org/mod_mbox/camel-users/201010.mbox/%3C1DC819B9-BA60-49CA-9518-E18EE951729D@nerdylorrin.net%3E

And there classified as a bug. For us this shows up when we have a Camel fetch like this:

sftp://easiakas.20.235/data1/easiakas/heracles_finvoice/download/invoice/?password=xxxxxx&delay=5000&delete=true&include=[^T].*\.zip

(or //data1/easiakas/heracles_finvoice/download/invoice/, doesn't matter, and even non-absolute heracles_finvoice/download/invoice/ won't work):

17:45:51,688 INFO  [CamelRouteBuilder] Started message processing in camel input route. Filename: test.zip uuid: 74143f3e-68fe-4f04-a784-087af57c735c
18:02:14,701 ERROR [SftpConsumer] Caused by: [org.apache.camel.component.file.GenericFileOperationFailedException - Cannot retrieve file: data1/easiakas/heracles_finvoice/download/invoice/test.zip]
org.apache.camel.component.file.GenericFileOperationFailedException: Cannot retrieve file: data1/easiakas/heracles_finvoice/download/invoice/test.zip

So it finds the test.zip, but it can't download it, since it's in the wrong directory or tries to change directory to a wrong one.


Version-Release number of selected component (if applicable):
JBoss SOA 5.3.0
Apache Camel 2.4.0


How reproducible:
Always

Steps to Reproduce:
1. Modify camel-quickstart:
jboss-esb-unfiltered.xml

replace <from> to:
<from uri="sftp://akovari@localhost//home/adam/xxx/?password=xxx&amp;delay=5000&amp;delete=true&amp;include=.*"/>

2. run ant deploy

3. See the server log:
