CORSFilter内部错误

Question

我使用这个库

http://software.dzhuvinov.com/cors-filter-configuration.html

<filter>
    <filter-name>CORS</filter-name>
    <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>

    <init-param>
        <param-name>cors.allowOrigin</param-name>
        <param-value>*</param-value>
    </init-param>

    <init-param>
        <param-name>cors.supportedHeaders</param-name>
        <param-value>authorization,content-type,x-http-method-override</param-value>
    </init-param>

    <init-param>
        <param-name>cors.maxAge</param-name>
        <param-value>1800</param-value>
    </init-param>

    <init-param>
        <param-name>cors.exposedHeaders</param-name>
        <param-value>authorization</param-value>
    </init-param>

    <init-param>
        <param-name>cors.supportedMethods</param-name>
        <param-value>GET, POST, HEAD, PUT, DELETE, OPTIONS</param-value>
    </init-param>
</filter>

<filter-mapping>

一切正常

除非我有一个返回错误代码500的内部异常：

content-length:10226
content-type:text/html;charset=UTF-8
date:Sun, 30 Apr 2017 21:44:29 GMT
status:500

GET 500内部服务器错误

如何让500个回复包含这些标题？
