Description
When attempting to extract metadata from a JPEG image with Tika OSGi Bundle, it fails with the following exception:

It seems to have something to do with the way the Drew Noakes MetadaExtractor is embedded into the Tika Bundle. I have tried supplying the metadata extractor as a separate bundle, even including the Adobe XMP Core inline and Tika does fails with the same issue.
You can reproduce the issue in the [Apache Sling CMS|https://github.com/apache/sling-org-apache-sling-app-cms] by starting the app, uploading a JPEG file and seeing the log at sling/logs/error.log
