Hi,
I looked at tika-server in a bit more detail, and I'm a bit concerned
about the dependency overhead it needs for the JAX-RS support:

That's about 7MB of middleware code. Do we really need all this? If
yes, who's going to review the licensing of all these dependencies and
come up with appropriate LICENSE/NOTICE files to include in the
tika-server jar?
The services exposed by tika-server are pretty simple and
straightforward, so I'm wondering if we could just replace all of the
above with just an embedded Jetty server, or even just the HttpCore
library [1].
