Description

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:

MyClass.java

public class MyClass {
    public Object[] getMyArray() {
        return new Object[]{"Hallo", "World", "!"};
    }
}

Accessing the property myArray with Simple:

<setHeader headerName="mySimpleHeader">
    <simple>body.myArray.length</simple>
</setHeader>
<log message="mySimpleHeader = ${header.mySimpleHeader}" />

Java:

final ProducerTemplate template = main.getCamelTemplate();
template.sendBody("direct:start", new MyClass());

Log:

[main] route1 INFO  mySimpleHeader = 1

The return value should be 3 instead of 1.
