> If the exchange body is an array, then {{body.length}} returns correctly the length of
the array. However, if the array is a property of an object, then not the correct value is
returned:
> {code:title=MyClass.java}
> public class MyClass {
>     public Object[] getMyArray() {
>         return new Object[]{"Hallo", "World", "!"};
>     }
> }
> {code}
> Accessing the property {{myArray}} with Simple:
> {code}
> <setHeader headerName="mySimpleHeader">
>     <simple>body.myArray.length</simple>
> </setHeader>
> <log message="mySimpleHeader = ${header.mySimpleHeader}" />
> {code}
> Java:
> {code}
> final ProducerTemplate template = main.getCamelTemplate();
> template.sendBody("direct:start", new MyClass());
> {code}
> Log:
> {noformat}
> [main] route1 INFO  mySimpleHeader = 1
> {noformat}
> The return value should be {{3}} instead of {{1}}.
