Re: IncomingFileTransfer recieveFile(..) throws "error in execution"

Not sure what version "4.1.0-rc1" denotes, so I tested with nightly  smack-4.1.0-beta3-SNAPSHOT-2015-02-12. Per your request, below is trace from  getCause() . Regression tested with previous smack-4.1.0-beta2-SNAPSHOT-2015-01-14 and results were same as below.   Also included  Raw Sent Packets and Raw Received Packets via SmackConfiguration.DEBUG = true, and my java class that implements FileTransferListener interface.
