Bug ID: 63968 Summary: ExpiresFilter: invalid cast Product: Tomcat 8 Version: 8.5.49 Hardware: PC OS: Linux Status: NEW Severity: normal Priority: P2 Component: Catalina Assignee: dev@tomcat.apache.org Reporter: cp...@timocom.com Target Milestone: ---- The getExpirationDate() Method of the ExpiresFilter throws a ClassCastException when the following conditions hold: 1. the request is ServletRequestWrapper 2. an inner request implements the interface org.apache.catalina.servlet4preview.http.HttpServletRequest Then the method will throw a ClassCastException in line 1296 of org.apache.catalina.filters.ExpiresFilter. Log Message observed: Our application uses a custom implementation of a ServletRequestWrapper. The ClassCastException logs that our custom implementation cannot be cast to org.apache.catalina.servlet4preview.http.HttpServletRequest Root Cause ========== The root cause is that if-conditon in line 1295 checks that innerRequest is an instance of servlet4preview.http.HttpServletRequest, yet in line 1296 the request (rather than the innerRequest) is casted. Out Tomcat Settings: ==================== We use Tomcat 8.5.49 with Connector-Protocol org.apache.coyote.http11.Http11NioProtocol. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
