Let's say I write an API for handling IO. DB or File or networking or anything really.
I get a failure, what do I do?
I can throw an exception, but this is important how do I know the user of my API will actually do the cleanup after me. I can't do the cleanup since this is a part of an API not the actual usage of the API. How can I give the user of this API the right set of hint that "you need to pay attention to this" without worrying too much.
Checked exceptions are that. A large part of the problem is when people use them for things that aren't important, but when they are important I can just declare a "throws" and know that someone will handle the exception along the chain.

With runtime exceptions I have no guarantee.
