--- Comment #4 from igor.muk...@gmx.de --- I never saw such a warning on the tomcat shutdown. And I just tested it, and I don't any warning still. But I see the line you meant in the code of StandardSession.doWriteObject: manager.getContext().getLogger().warn( sm.getString("standardSession.notSerializable", saveNames.get(i), id), e); In the debugger I see the line executed not I don't see any output in my logs. Really strange. (This is a Spring Boot project with devtools) Still I think telling the name of the attribute which caused the problem on the tomcat start would be helpful, because one would know right away what the problem is, and he does not need to know that there was a message in the shutdown log which nobody every reads. -- 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
