Interface ExceptionHandler

public interface ExceptionHandler

Strategy for handling exceptions that arise in asynchronous or background processing where a normal exception propagation path does not exist, such as in a Consumer's polling thread.

Unlike the route-level ErrorHandler, which handles exceptions thrown by processors inside a route, ExceptionHandler is used by infrastructure code (consumers, schedulers, Quartz jobs, background threads) that cannot propagate exceptions through the normal routing chain. The default implementation logs the exception and continues; custom implementations can re-route, alert, or escalate as needed.

Implementations must not throw exceptions from their handleException methods, because the handler is typically called from within an existing catch block and a secondary exception would mask the original failure.
