This looks like the old type erasure problem - the returned map is of a private class, so clojure looks for a public version of the "put" method in one of the interfaces/base classes - but does an exact comparison on parameter types, so put(String, String) doesn't match put(Object, Object) and the search fails. You might think that the Reflection API would provide a way of looking for methods that you could call with the types given, instead of just exact match, but using getMethod() or getDeclaredMethod() instead of looping and comparing manually yields the same result.
However, as mentioned at http://christerblog.wordpress.com/2010/02/27/java-reflection-matching-formal-parameter-list-to-actual-parameter-list/ , the Coherence Common Incubator project has a ReflectorHelper module that provides a solution (at least in the case of constructors); I''m thinking Clojure could adapt/adopt that solution.
