I have migrated my google app engine application from java ee 8 to jakarta 10. I used to manage sessions using <sessions-enabled>true<sessions-enabled> tag. But then ever since I migrated my application to jakarta 10 and started using the java 21 runtime, app-engine apis do not work. Of which behind the scenes I need app engine apis to be able to use <sessions-enabled>. So instead of storing my session attributes using the standard way
session.setAttribute(USERNAME, username);
I started using http cookies to store my attributes. this was the only change I made with regard to session management. So if I deploy for the first instance. I can log in and my application works well even after I log out. But if I deploy new changes , my application fails to start up , until I clear browser cache. Is there any way I can solve this. This is the error I get
