Claus Ibsen commented on CAMEL-4576:
------------------------------------

You wanna create a new exception instance on the fly and provide a String for its constructor. And that String parameter is constructed using the Simple language.

Which use-case do you need this for? Eg to use <throwException> in a Camel route?

>                 URL: https://issues.apache.org/jira/browse/CAMEL-4576
>             Project: Camel
>          Issue Type: Improvement
>          Components: camel-core
>    Affects Versions: 2.8.1
>         Environment: N/A
>            Reporter: David J. M. Karlsen
>              Labels: exception, throwException, xml
>
> When throwing exceptions there are more options in the java DSL (one has full control) than in the XML where you can only reference an exception instance.
> It would be useful to be able to construct the exception and throw it, so that one could add messages to it - preferably like:
> {noformat}
> throwException class="someEx" message="someProblem ${body} ${in.header.someHeader}
> {noformat}
