The biggest annoyance with Java checked exceptions IME is that it’s impossible to define a method type that’s generic over the type of exception it throws. Checked exceptions should indicate conditions that are expected to be handled by the caller. If a method is throwing a laundry list of checked exceptions then something went wrong in the design of that method’s interface. |

Exactly. If Stream methods like filter() and map() could automatically "lift" the checked exceptions thrown by their callback parameters into their own exception specifications, it would solve one of the language's biggest pain points (namely: Streams and checked exceptions, pick one).
