-----------------------------------
Assignee: Claus Ibsen
> camel-bean - Add better support for invoking varargs methods
> ------------------------------------------------------------
>
> Key: CAMEL-21817
> URL: https://issues.apache.org/jira/browse/CAMEL-21817
> Project: Camel
> Issue Type: Improvement
> Components: camel-bean
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 4.11.0
>
>
> {code:java}
> from("timer:java?period=5000")
> .setBody()
>
> .simple("${bean:type:java.util.Arrays?method=asList(${exchangeProperty.CamelTimerCounter},
> \"${exchangeId}\",\"New event ${exchangeId} generated at
> ${exchangeProperty.CamelTimerFiredTime}\")}")
> .log("${body}"); {code}
>
> This ends up invoking asList(...) on Arrays that is a vararg, but is visible
> as Object[] at runtime. So we need to have some special code in camel-bean to
> detect this to ensure it invokes the method correctly, creating a single
> Object[] array of the 3 args
