ClassCastException when passing a HashMap to a Java function

I want to call a Java function (provided by SVNKit) with the following signature:

public abstract long getFile(String path,
                             long revision,
                             Map properties,
                             OutputStream contents)
                      throws SVNException

The parameters properties and contents are optional. In Clojure I call this function with:

(defn read-file
  ""
  [repository path]
  (let [properties (java.util.HashMap.)
        baos (java.io.ByteArrayOutputStream.)]
    (.getFile repository path -1 properties baos)
    (.size baos)))

I get a ClassCastException on the properties parameter. When I leave it out (use nil instead of properties) it works fine. The ClassCastException doesn't give any information about what class it is expecting.

Any ideas?

According to the SVNKit javadoc at http://svnkit.com/javadoc/index-all.html

there is not a method with the signature you listed. The closest seems to be:

public abstract long getFile(String path,
                             long revision,
                             SVNProperties properties,
                             OutputStream contents)
                      throws SVNException

from http://svnkit.com/javadoc/org/tmatesoft/svn/core/io/SVNRepository.html
