Summary

0004953: CGIServlet error handling

Description

When CGIServlet parses headers set by the script, and finds an error code, it immediately writes a custom error page to the response. This causes 2 problems:

1. The CGI (ex wordpress with cgi-php) writes it's own informational 500 error page, which does not get displayed at all.
2. HTTPServletResponseImpl.sendError opens a response writer, then CGIServlet attempts to open a reponse outputstream, resulting in the error below:

[12-02-03 16:18:31.098] {http://*:8080-16} [^] javax.servlet.ServletException: java.lang.IllegalStateException: getOutputStream() can't be called after getWriter().
