FacesMessage.Severity always set to ERROR after ValidatorException

The severity of messages is always set (overwritten) to SEVERITY_ERROR when a ValidatorException is thrown during validation. In org.apache.myfaces.view.facelets.compiler._ComponentUtils I see that we always call

facesMessage.setSeverity(FacesMessage.SEVERITY_ERROR);

when processing a ValidatorException. This might make sense if we're assuming that all faces messages default to some other severity, but it doesn't seem right to me that we're overwriting user-set message severities. For example, given the following custom validator:

public void validate(FacesContext context, UIComponent component, Object value) {
if (value == null)

{ List<FacesMessage> messageList = new ArrayList<>(); messageList.add(new FacesMessage(FacesMessage.SEVERITY_INFO, "ValidatorException#SEVERITY_INFO", "ValidatorException#SEVERITY_INFO")); throw new ValidatorException(messageList); }

}

The severity of the custom message will always be set to SEVERITY.ERROR. I don't see much guidance in the spec on this, but Mojarra behaves differently - it does not overwrite custom FacesMessage severities.
