The volume of logging in production systems is such is that it is impractical to act on individual exceptions. You would typically send log events to a centralized logging service or have an agent-based code monitor logs locally for well know sequences or error codes. And that's where Java exceptions can be improved - a built-in facility to assign error codes so that downstream tools can handle exceptions based on a rule book which takes application-specific error codes into account.
