The new release 1.15 now fails in Apache Camel when we run our OSGi tests

The problem is that tika-bundle has an import on package

org.slf4j.event;version="[1.7,2)"

And that package does not exists in 1.7.x. It looks like its a new thing that comes in slf4j 1.8 onwards but they have only alpha releases
http://search.maven.org/#search%7Cga%7C1%7Cfc%3A%22org.slf4j.event%22

It would be good to get this fixed. I wonder if that event package is really needed? And if not then please remove that import in the OSGi manifest file.

Otherwise you would need to depend on slf4j-api version 1.8 which is still not released in GA and not widely in use. I would suggest to be compatible with slfj4 1.7 so the Tika upgrade from eg 1.14 to 1.15 is a smooth upgrade for end users.
