What (small set of) steps will reproduce the problem? (do (proxy [clojure.lang.IPersistentVector] []) nil)

What is the expected output? What do you see instead? Expected: nil Observed: java.lang.ClassFormatError: Duplicate method name&signature in class file clojure/proxy/java/lang/Object$IPersistentVector

Changed duplicate methods detection to not take the return type into account. Changed stub generation to always generate a stub for the most specific return type.

patch applied - svn 1328 - thanks!

with patch93bis.patch proxy emits bridge methods for covariant return types (except for the method whose return type is the most specific)
