1 - If an AQL expression has a warning, nothing is displayed (if something crashes it is displayed, everything else is considered ok).
2 - If an AQL expression returns a collection, we display its real Java type (ArrayList for example) that's an implementation detail.
3 - If the result of an evaluation is an EObject, we display the name of its java Class (again, an implementation detail) not the qualified name of its type.
4 - Pretty much everything in AQL is represented using a diagnostic with children so we need to be able to create MultiStatus object to represents all the error s or warnings found.

For the problems 1 and 3, see that SiriusEvaluationTask.createResultStatus(Object) can only create OK status not WARNING or ERROR ones (an error can only be triggered by AQL throwing an exception). In AQLSiriusInterpreter, we have all the relevant pieces of information to display a proper warning or error message and we discard them to give the result to SiriusEvaluationTask.
