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
