Hadrian Zbarcea commented on CAMEL-1823:
----------------------------------------

@Johan, I think you're on the right track, but I am not sure I like the internal exception and I'd try to avoid it if possible. The reason is that the predicate does not have exception semantics. Interesting hack nevertheless.

> As someone suggested on the user forum.
> Letting {{doCatch}} be able to catch and react to a predicate as well. Currently it *only* reacts when an exception has been thrown.
> Letting it react to predicates as well will really set it high over its Java counter part.
> {code}
> doTry()
>    .beanRef("myBean")
>    .to("activemq:queue:foo")
> .doCatch(body().isNull())
>    .to("log:foo?level=WARN")
> .end()
> {code}
