Condition for error is almost same. I think method 'archive.getExtractionLog()' is reason for error. It not check, if log is log of correct file but use log for processing.
So method 'archive.getExtractionLog()' not reliable to parse log.
I think you must change and add use of unique file id like file hash, so correct file and log can always identified.
