The executeAndFetch
method expects a model class as a parameter. It expects to use the built-in converter framework to convert the fetched database values to the properties in the model class. It doesn't expect to create a simple list of primitives, as in your example.
The method you are looking for is the executeScalarList
method. If you use that, it should work as you expect in your example.
List<Long> longList = myQuery.executeScalarList(Long.class);

Thanks - this used to work just fine in our version - we must have patched this so that the API was simpler /more consistent. We know the return type - why have two methods to get at a List<> of something
