Our software uses Tika to parse large and diverse sets of customer files. Amongst these files we have eml files which are embedded within msg files. These eml files have a media type of message/x-emlx as detected by Media Detector.
From Tika 1.7 onwards the binary mime attachment data of the file within the parent msg file is parsed as text, this did not happen with Tika 1.6 or prior versions. This is causing huge volumes of meaningless characters to be passed through to our content handler.
