In layered code, if not recoverable by the current layer, you should always encapsulate checked exceptions thrown by a lower layer - translated into an exception of the current layer (maybe generalized). This simple rule is often declared as overhead. I don't get that. I like code to be precise. The only situations where this gets complicated are those, where the rule is violated. And I think, the rejection of checked exceptions is often based on experiences with bad API design.

Exception handling must be trained and educated. There is no silver bullet.
