-----------------------------------------
Summary: Exceptions on routes SFTP and SEDA or DISRUPTOR (probably
others)
Key: CAMEL-8887
URL: https://issues.apache.org/jira/browse/CAMEL-8887
Project: Camel
Issue Type: Bug
Components: camel-ftp
Environment: Camel running on Windows, polling Linux server.
Reporter: Gwenhaël PASQUIERS
Priority: Critical
When polling from SFTP, if the exchanges are sent to asynchronous routes (seda,
disruptor) many different types of exceptions happen everytime, when
retrienving the content or deleting / moving / renaming the polled files.
The cause is that when routes are executed asynchronously, concurrent calls to
SftpOperations are made. It looks like SftpOperations as well as ChannelSftp
(Jsch) are not thread-safe. Sftp commands are either colliding, and sometime
are invalid at the protocol level.
One workaround is to make SftpOperations thread-safe by making its methods
synchronized.
Maybe there is another better place for a fix but i leave that to the
specialists.
