Simon: Generated code might legitimately throw either IllegalArgumentExceptions or IllegalStateExceptions with appropriately descriptive error messages, but if it's throwing a descriptionless NullPointerException, it has a bug in it. Even if you eventually find a workaround, please file a JIRA for this issue so that the code gets fixed.
