"IllegalAccessError when using an instrumented class"

Hi all,
I am trying to instrument https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/Compiler.java https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/Compiler.java
I am using the following code:
ClassPool cp = ClassPool.getDefault();
CtClass ctClazz = cp.get("clojure.lang.Compiler");
ctClazz.addMethod(CtNewMethod.make("public String foo (){return \"foo\"; }", ctClazz));
return ctClazz.toClass();
I am calling getDeclaredMethod on the returned class and invoke on the method to call foo() which throws:
IllegalAccessError tried to access class clojure.lang.Compiler$DefExpr$Parser from class clojure.lang.Compiler clojure.lang.Compiler.<clinit>
(Compiler.java:102)
Javassist's docs state that it does not work with inner classes, which I suspect to be the problem here.
Or rather it could be a ClassLoader problem. Unfortunately I know little about classloaders.
Any pointers would be appreciated.
Thanks!
