Maybe someone else can explain the reasoning for this behavior, but what's
happening is:
your errorHandler is handling the exception in route 2, but it doesn't see
any exception handlers (none declared on the immediate route, and none
globally defined).
so it just tries redelivery, marks it as "FAILURE_HANDLED". When the first
route gets the exchange, it will decide what to do with it... and since the
route first handling the error marked it as "FAILURE_HANDLED" the first
route doesn't try to do anything with it and propagate the exception back
up.
To get the behavior you're looking for, move the onException clause to be
global.
