I get an InvocationTargetException the first time I query the
datastore after starting the dev server.
My app works fine, but I feel like the exception slows down the
startup time and is also probably a bad thing.
My query is simple its just:
Query q = pm.newQuery(Question.class);
List<Question> cards = (List<Question>) q.execute();
And on the call to execute i get this exception, which appears as an
Info message in my logs:
