camel-bindy @DataFeild trim parameter does not affect to the last column in the csv line

Issue

This is the Java Bean with @CsvRecord(separator = ",").
Please note that all of @DataField has trim=false.

    @DataField(pos = 1, trim = false)
    private String orderNr;

    @DataField(pos = 2, trim = false)
    private String clientNr;

This is the toString() method.

    @Override
    public String toString() {
        return "Order:" + this.orderNr + ":" + this.clientNr +";";
    }  

By executing this camel route here,

  from("timer://foo?repeatCount=1")
.setBody(constant("a  ,b  \n"))
.unmarshal(camelDataFormat)
.log("${body}");

expected result is

Order:a  :b  ;

but the actual result is

Order:a  :b;
