[jboss-user] Illegal access (timeout error)

Hi All, We are running Jboss 4 and we get the following error when we leave a client session (browser) idle for about 40 minutes. The symptoms are similar to a session timeout error that one usually gets but it doesn't seem to be that. Can someone please assist. The stack trace is included. java.lang.SecurityException: Illegal access at org.apache.jsp.www.admin.GIQteFind_jsp._jspService(org.apache.jsp.www.admin.
