> Hi,

> Seems like Tika tries to parse this file as Java class file, but that obviously doesn't work.
> I've tried to create custom-mimetypes.xml file like this :
> <?xml version="1.0" encoding="UTF-8"?>
> <mime-info>
> <mime-type type="application/octet-stream">
> <_comment>Mac OSX jnilib</_comment>
> <glob pattern="*.jnilib"/>
> </mime-type>
> </mime-info>
> and after I repack tika-app-1.4.jar with this file in org.apache.tika.mime folder, the problem still
> exists.
> Jnilib file is actually from the ActiveMQ 5.8.0 binary found in bin/macosx/libwrapper.jnilib
