如何在Jetty 7/8中设置JSP响应语言环境？

jsp

如果我在servlet中以编程方式设置HTTP响应语言环境，如下所示：

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
    throws IOException, ServletException
{
    response.setLocale(SOME_LOCALE);
    // .. etc
}

然后在Jetty 7及更高版本中，任何尝试通过表达式$
{pageContext.response.locale}读取该语言环境的JSP都将获取服务器的默认语言环境，而不是上面的设置。如果我使用Jetty
6或Tomcat，则可以正常工作。

这是演示该问题的完整代码：

public class MyServlet extends HttpServlet {

    // Use a dummy locale that's unlikely to be the user's default
    private static final Locale TEST_LOCALE = new Locale("abcdefg");

    @Override
    protected void doGet(final HttpServletRequest request, final HttpServletResponse response)
        throws IOException, ServletException
    {
        // Set a known response locale
        response.setLocale(TEST_LOCALE);

        // Publish some interesting locales to the JSP as request attributes for debugging
        request.setAttribute("defaultLocale", Locale.getDefault());
        request.setAttribute("testLocale", TEST_LOCALE);

        // Forward the request to our JSP
        getServletContext().getRequestDispatcher("/index.jsp").forward(request, response);
    }
}

和JSP：

<html>
    <head>
        <title>Locale Tester</title>
    </head>
    <body>
        <h2>Locale Tester</h2>
        <ul>
            <li>pageContext.request.locale = '${pageContext.request.locale}'</li>
            <li>default locale = '<%= request.getAttribute("defaultLocale") %>'</li>
            <li>pageContext.response.locale = '${pageContext.response.locale}' (should be '<%= request.getAttribute("testLocale") %>')</li>
        </ul>
    </body>
</html>

Tomcat返回此信息（正确）：

Locale Tester

    pageContext.request.locale = 'en_AU'
    default locale = 'en_US'
    pageContext.response.locale = 'abcdefg' (should be 'abcdefg')

码头7（错误地）返回此：

Locale Tester

    pageContext.request.locale = 'en_AU'
    default locale = 'en_US'
    pageContext.response.locale = 'en_US' (should be 'abcdefg')

FWIW，我使用Jetty / Tomcat Maven插件进行了上述所有测试。

我通过Jetty邮件列表发现这是Jetty
7中的错误，现已修复。
