> The counter will be 2.
> {quote}int counter = 0
> from("timer://testRoute2?repeatCount=1").routeId('testRoute_timer2').autoStartup(true)
> .onException(IllegalArgumentException).onWhen(\{it.getException().toString().contains('foo')})
> .process({
> counter++
> println "print in onException foo $counter"
> }).handled(false)
> .end()
> .log('in testRoute2')
> .process({
> println 'before throwing exception'
> throw new IllegalArgumentException("foo")
