What does Java do in the case of out-of-memory exceptions in small
embedded systems (e.g., Java smartcard with 256 bytes RAM), where
there might not be space free for allocating an exception object?
Ada's exception mechanism sounds to me less comfortable, but more
foolproof here, as it does not rely on an operational heap. Also
remember that Ada was designed to allow using a heap-free subset
of the language for high-assurance applications (you do not want
to rely on malloc() in pacemakers and chemical process control
software).
