      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>
