Resolve problems with Java interop

resolve.txt

Given the following:

(defn test-function []
  (.info logger "hello test"))

(defn -testResolve [this]
  (let [fn (resolve (symbol "test-function"))]
    (apply fn [])))

And an interface with:

void testResolve();

If I call this from the REPL:

com.pegby.service.clj.boardUpdate=> (-testResolve nil)
1512720 [main] INFO com.pegby.service.clj.boardUpdate  - hello test
1512720 [main] INFO com.pegby.service.clj.boardUpdate  - hello test
nil

Great!

However, from my unit test:

BoardUpdateFunctions f = new BoardUpdateFunctions();
f.testResolve();
