    Workaround Description: 
implement private method:

    private  String getAttribute(String alias,Map<String, List<String>> attributeValues) {
        if (attributeValues == null) return null;

        List<String> values = attributeValues.get(alias);
        if (values==null||values.size() == 0) {
            return null;
        } else if (values.size() == 1) {
            return (String) attributeValues.get(alias).get(0);
        } else {
            throw new RuntimeException("Attribute has multiple values");

        this.email = getAttribute("email",principal.getAttributeValues());
