Description

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...
