Я пытаюсь перейти от Tomcat 7 к Tomcat 8. Я использую maven как инструмент сборки. От Tomcat 8 Maven Plugin for Java 8 Я вижу, что можно использовать Tomcat7-maven-plugin с Tomcat8. Тем не менее, здесь речь идет о жалобах Джаспера на недопустимую версию JSP, когда она не должна на самом деле.JSP 2.3 с Tomcat 8

С Tomcat 8 uses Jasper 2 для реализации JSF 2.3 и из приведенного ниже кода Jasper 2: -
public void visit(Node.JspRoot n) throws JasperException {
JspUtil.checkAttributes(TagConstants.ROOT_ACTION, n, jspRootAttrs, err);
String version = n.getTextAttribute("version");
if (!version.equals("1.2") && !version.equals("2.0") &&
!version.equals("2.1") && !version.equals("2.2") &&
!version.equals("2.3")) {
err.jspError(n, MESSAGES.invalidJspVersionNumber(version));
}
visitBody(n);
}
Я подозреваю, что версия Джаспера не может быть правильной, на которую ссылаются c используя ошибку, но у меня нет способа оценить это. Любые ссылки оцениваются!
