Description

Cannot evaluate length on java.lang.String[] in simple
I suspect this is because this is part of the language itself. But still, why not?

repro step

run this:

?xml version="1.0" encoding="UTF-8"?>
<routes xmlns="http://camel.apache.org/schema/spring" >
    <route>
        <from uri="timer:test?repeatCount=1"/>
        <setBody>
            <groovy>[[2, "Chaine_avec_des_underscores", 12, "c"], ["d4", "e5", "f6"]]</groovy>
        </setBody>
        <split>
            <simple>${body}</simple>
            <setHeader headerName="splittedColumn1">
                <simple>${body[1].split("_")}</simple>
            </setHeader>
            <log message="${header.splittedColumn1.length}"/>
        </split>
    </route>
</routes>
