Was faced with the same error when trying to launch an AsyncTask and found that the reason it would fail was that an unrelated thread would throw an unhanded exception early on. It seems the AsyncTask and the other thread (used to fetch ad banners) shared resources and when the ad thread misbehaved it made the class loader misbehave as well.
