Ajax update has no effect, Firefox errors: XML or text ad is not at the beginning of the object

I have a small form that will receive values ​​from a class. However, clicking the button will not update selectOneMenu.

Updating the form will correctly populate the menu with the correct elements.

I expected

update="instrument"/>

to refresh the contents of the menu. But I think I'm missing something. Note that the method in the bean is called when the button is clicked. The list is populated, and int is set when an item is selected.

<h:form id="listForm">

            <p:outputLabel for="instrument" value="Instrument " />
            <p:selectOneMenu id="instrument" value="#{tradeFactory.intInstrumentID}" style="width:150px">
                <p:ajax listener="#{tradeFactory.onInstrumentChange(tradeFactory.intInstrumentID)}" update="instrument" />
                <f:selectItem itemLabel="Select Instrument" itemValue="" noSelectionOption="true" />
                <f:selectItems value="#{tradeFactory.instrumentID}" />
            </p:selectOneMenu>
            <p:commandButton value="Update" actionListener="#{tradeFactory.getInstrumentIDs()}" update="instrument"/>

Update function

@PostConstruct
public void getInstrumentIDs() {
    Set<Integer> s = trades.keySet();

    instrumentID.clear();

    s.stream().forEach(i -> instrumentID.put(String.valueOf(i), String.valueOf(i)));
}

Ajax update error caused by double XML prolog in ajax response:

<?xml version='1.0' encoding='UTF-8'?>
<?xml version='1.0' encoding='UTF-8'?>

Can be only one.

/ JSF API . , / API impl.

, Maven barebones servletcontainer (Tomcat) , Mojarra (2.2.11) javax.faces.jar, :
