Juergen Hoeller opened SPR-14323 and commented

In contrast to AbstractMessageChannel, our ExecutorSubscribableChannel does not consistently wrap handler-thrown Errors in a MessageDeliveryException: It propagates the latter to ExecutorChannelInterceptors but rethrows the plain Error. Let's align this for 4.3.

Affects: 4.2.6, 4.3 RC2
