Web Server crashes when a customized JSP page for Access Manager is deployed in Sun Java System Web Server. The problem occurs when using a Web Server version prior to 6.1 SP8. The problem is due to a known problem in Sun Web Server that is unrelated to Access Manager server. If the JSP has calls to HttpServlet.getScheme or HttpServlet.service, the Web Server can crash.
Solution: Upgrade to Web Server 6.1 SP8.
