That would also be my recommendation. BTW, I just wrapped up Lucene, Sesame (RDF data store), and Java DB in one package (I wanted RDF+geolocation+search of text in RDF triples), and also put Clojure and Scala wrappers around my Java wrapper.

If you are using Clojure, Scala, JRuby, etc., might as well take advantage of great Java libraries.
