> The utility method org.apache.camel.util.ExchangeHelper.copyResults() is use by many
core classes. However, this method does not properly support MEP InOptionalOut.
> Assuming in an InOptionalOut exchange, having no out message means just that -- no out
message should be sent, then the following lines in this method
> {code}//
>             Message out = source.getOut(false);
>             if (out != null) {
>                 result.getOut(true).copyFrom(out);
>             } else {
>                 // no results so lets copy the last input
> {code}
> should be changed to:
> {code}//
>             Message out = source.getOut(false);
>             if (out != null) {
>                 result.getOut(true).copyFrom(out);
>             } else if (result.getPattern() == ExchangePattern.InOptionalOut) {
>                 result.setOut(null);
>             } else {
>                 // no results so lets copy the last input
> {code}
