Ah no wonder! I was looking at the wrong documentation for asm. On 02/04/2014, at 1:41, A.

Strange behaviour for proxy when two abstract classes are passed in
I know this is a silly example but I am curious to know what is happening with the proxy method. I have set up two calls to proxy: 1. (def cp (proxy [java.util.AbstractMap clojure.asm.ClassVisitor] [])) 2. (def cp (proxy [clojure.asm.ClassVisitor java.util.AbstractMap] [])) The first call is fine and it return cp. The second call gives me an exception. clojure.lang.Compiler$CompilerException: java.lang.IncompatibleClassChangeError: Implementing class, compiling:(/private/var/folders/dd/qfdy6sbn3mlgk20vcxc3j0ljnpxsqr/T/form-init4780219965491827451.clj:2:5) java.lang.IncompatibleClassChangeError: Implementing class java.lang.ClassLoader.defineClass1 ClassLoader.java java.lang.ClassLoader.defineClass ClassLoader.java: 800 java.lang.ClassLoader.defineClass ClassLoader.java: 643 clojure.lang.DynamicClassLoader.defineClass DynamicClassLoader.java: 46 clojure.core/get-proxy-class core_proxy.clj: 262 -- You received this message because you are subscribed to the Google Groups Clojure group.
