Moving files on FTP not working

Moving files stored on a ftp server to another directory specified by the move parameter is not working in camel versions 2.10.3, 2.10.4-SNAPSHOT and 2.11-SNAPSHOT.
(The ftp user got write permission.)
Whereas the file is moved as expected when using version 2.10.2

The stacktrace I got when executing the test on camel version 2.10.3:

The anonymized test case:

}
});
Thread.sleep(3000);
context.stop();
