Available as of Camel 2.10.4/2.11

When Camel error handler handles an error such as Dead Letter Channel or using Exception Clause with handled=true, then Camel will decorate the Exchange with the route id where the error occurred.

String failedRouteId = exchange.getProperty(Exchange.FAILURE_ROUTE_ID, String.class);

The Exchange.FAILURE_ROUTE_ID have the constant value CamelFailureRouteId.

This allows for example you to fetch this information in your dead letter queue and use that for error reporting.
