Jürgen Enge created TIKA-1184:
---------------------------------

             Summary: Infinite halt on parsing old files (e.g. mp3, ms-dos drivers, ...)
                 Key: TIKA-1184
                 URL: https://issues.apache.org/jira/browse/TIKA-1184
             Project: Tika

            Reporter: Jürgen Enge


tika hangs on identifying several types of files. the following example is an mp3 file with
corrupt metadata. other filetypes which have the same problem are for example MSDOS device
drivers (*.sys)
i am not into java programming, but my guess would be, that tika is trying to seek() within
a file and the target position is greater than filesize. 

> java -jar tika-app-1.4.jar -m /u01/fk/xd/2/c/16866bc96e6a316d8cbdbd7ca2ce1e
[hangs forever without error message]

ffmpeg gives some warnings about duration errors...
