Better implementation of getRealDeclaringClass()

        private Class<?> getRealDeclaringClass(Method m) throws NoSuchMethodException
        {
            // Get the method's current declaring class
            Class<?> dcl = m.getDeclaringClass();
            // Special handling for equals and hashCode() -- first unmangle the name
            String name = m.getName().contains("equals") ? "equals" : m.getName().contains("hashCode") ? "hashCode" : null;
            if (name != null)
            {
                // Walk up the class hierarchy to the first non-proxy class
                while(dcl.getName().contains("javassist"))
                    dcl = dcl.getSuperclass();
                // Now get the declaring class of the unmangled name
                dcl = dcl.getMethod(name,m.getParameterTypes()).getDeclaringClass();
            }
            return dcl;
        }
