As a thought excercise, it is possible to have add a last Resource, that will query all pending exceptions in all previous contextes, or make this context block once all beforeCheckpoint are done and there is nowhere to report exceptions.

It is possible to add query method to JDK contextes without changing public context interface. The same way, the alternative won't require changes in the public API (it will be a convention between JDK contextexes and the well-known resource).
