The match value for .fts file format in tika-mimetypes.xml is "SIMPLE = T".
Tika detected a .fts file as application/octet-stream. On verifying the header I found the value to be "SIMPLE = T"(just 16 spaces before = and T)
I tried the following changes-
Change 1) Updated the existing match value. But the build failed
Change 2) Added a new match value <match value="SIMPLE = T" type="string" offset="0"/> after the existing one.
But now, tika returns empty value. It neither identifies the file as .fts nor as application/octet-stream.
