We've included kettle-6.0.0.0-353 in our Tomcat webapplication to do data transformation.

Until recently it worked, now we get

org.pentaho.di.core.exception.KettleXMLException:

Unable to load the job from XML file

[file:///home/superx/tomcat/webapps/superx/WEB-INF/conf/edustore/db/module/sva/etl/sap_hr/sap_hr_sva.kjb]

Unable to get VFS File object for filename 'file:///home/superx/tomcat/webapps/superx/WEB-INF/conf/edustore/db/module/sva/etl/sap_hr/sap_hr_sva.kjb' : Unknown scheme "sftp" in URI "{1}". 

I don't understand what's happening SFTP isn't used.

Any suggestions?
