Description

When doing the following in a route:

.onException(HaltOperationsError.class)

.maximumRedeliveries(10)
.backOffMultiplier(10) // 1 s base

.handled(true)
.delay(10)
.log("Halting operations for some time")
//.process(new RouteStoppingProccesor("PostProcessorRoute"))
.end()

I get the following stacktrace:
ERROR ContextLoader - Context initialization failed

I think this is a minor error, but it would be nice to know if something could be done with it so that the errormessage is easier to understand.
