Allow specification of a timeout value for service invocation, such that:

• An invocation of a reference allows for a timeout with optional interrupt if the timeout expires.
• Execution time is available in a Camel route and checked during execution. If timeout lapses, a user-defined handler should be available for handling processing from there.
• The timeout value can be specified by a client of the service (propagated via header or similar mechanism)

See forum thread for additional info.
