using javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL causes viewParam to be null

I'm trying to switch an application from WildFly 13 (Java EE 7, JSF 2.2.15) to WildFly 16 (Java EE 8, JSF 2.3.9). Tried both PrimeFaces 6.2 and 7.0

In web.xml javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL is set. JSF 2.2 version working fine, switching to WildFly 16 this different behavior. A simple example follows:

Instructions: access: http://localhost:8080/primefaces-test/?tipo=U&test=Bah click first button, click second button. after ajax the viewParam value in the bean is null, even it is filled within the url.

Sample project (Jetty): https://github.com/erickdeoliveiraleal/primefaces-test/tree/update

XHTML

 <!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:p="http://primefaces.org/ui"
    xmlns:h="http://java.sun.com/jsf/html">
<f:metadata>

    <f:viewParam name="test" value="#{testView.testString}" />
    <f:viewAction action="#{testView.inicializar}" />

</f:metadata>
<h:head>
    <title>PrimeFaces Test</title>
</h:head>
<h:body>

    <h:form id="cadastro">
        <h:commandButton value="click me"
            action="#{testView.inserirNaLista()}">
            <f:ajax execute="@form" render="@form" />
        </h:commandButton>
        <p:commandButton
            value="click me - 2 (this button causes the null value)"
            action="#{testView.inserirNaLista()}" />

    </h:form>


</h:body>
</html>

Bean

@ManagedBean(name = "testView")
@ViewScoped
public class TestView implements Serializable {
    private String testString;

    public void inicializar() {
        System.out.println("initializing: " + testString);

    }

    public void inserirNaLista() {
        System.out.println(testString);
    }

    public String getTestString() {
        return testString;
    }

    public void setTestString(String testString) {
        this.testString = testString;
    }

}
