I've been testing this and there is a dependency collision since Tika 1.3:

[INFO] Checking compile classpath
[WARNING] Found duplicate classes in [org.apache.xmlbeans:xmlbeans:2.3.0,xml-apis:xml-apis:1.3.03] :
[WARNING]   org.w3c.dom.DOMConfiguration
[WARNING]   org.w3c.dom.DOMStringList
[WARNING]   org.w3c.dom.TypeInfo
[WARNING]   org.w3c.dom.UserDataHandler

Looking into resolving that.

Offending dependencies from Tika are org.apache.poi:poi-ooxml:jar:3.8:compile and com.drewnoakes:metadata-extractor:jar:2.6.2:compile.
