Description

Camel cannot fetch files from users home directory when using readlock=changed.

Route from URI is defined like this:

<from uri="sftp://testi@server:22?password=password&include=PSOP_123-.*\.(xml|pdf)&delete=true&readLock=changed&readLockTimeout=360000&readLockCheckInterval=180000&readLockMinAge=10s&maxMessagesPerPoll=100"/>

And from TRACE logs I can see stuff like this:

User home directory contains only 1 file, which does match to include parameter. It does seem, that camel-ftp is trying to check file readlock from the server root.

When placing the files to a subdirectory in users home, this does not happen.
