      When ArrayList is passed to a proxied object, CLAC creates another proxy for the passed list. The problem is, that this proxy is ForgeProxy, but behaves like unwrapped object (it doesn't have getHandler() method). When the same list is being retrieved from the proxied object, CLAC throws NPE in stripClassLoaderAdapters() method, because isForgeProxy(list) returns true, but getForgeProxyHandler(list) is null.
