If you are aware of particular situation, you can handle it. If you aren't aware of a particular situation at best you log the problem and skip the operation.

If you are aware of particular situation, you can handle it. If you aren't aware of a particular situation at best you log the problem and skip the operation. That's pretty straight forward and is still the same approach. For example, I might just catch every single Network exception, log it, add a timeout, and retry the operation. I'm not playing wack-a-mole and I don't care in the handler which of the thousands of methods called in my operation actually raised the exception. The point is one should not be looking at what exceptions the methods throw but instead what exceptions can be handled. One set is very large the other set is very small. This applies equally well to server software.
