--- Comment #1 from Mark Thomas <ma...@apache.org> --- Comment on attachment 35693 --> https://bz.apache.org/bugzilla/attachment.cgi?id=35693 Tomcat 9 log, regarding Server Sent Events The NPE on shutdown looks like a Tomcat bug to me and we should get that fixed. The IOException on connection close is exactly what should happen. This is an asynchronous request using blocking I/O (WebSocket is not involved here based on the stack trace) as far as I can tell so Tomcat has no way of knowing the socket is closed until the app tries to write to the socket. At that point an IOException is thrown. The app does't handle it so Tomcat logs it. This is all as designed. I'd expect either the app or possibly Spring to handle this case. -- 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
