This event is triggered when an exception occurs within the scope of the given Session. Its handler must be implemented by the application developer.
NOTE: This event will be triggered by a callback thread pool within the API. Although the current thread pool has only a single thread in it, the developer should not assume that the triggering of this method will be done in a serial manner. This means that in principle, these methods can be called at any time and it is the developer's responsibility to make this call thread-safe.
