An "IllegalStateException: Session was invalidated" - exception is thrown after session was already invalidated

[stefan-g]

I have a /logout rest endpoint that invalidates a session by using HttpSession#invalidate(). Sometimes (10 out of 1000 requests) the following IllegalStateException is thrown.

java.lang.IllegalStateException: Session was invalidated

The exception occurs in combination with spring cloud gateway (netflix). It's seems that the way spring cloud gateway is forwarding the request causes some troubles in this case.

The used components are spring boot 3.2.3, spring cloud dependencies 2023.0.0, Redisson

I found a similar case here spring-projects/spring-security#9128 (comment) but there it is related to spring security.

The exception can be reproduced by the following demo app (tested on windows 11). check readme.md for details.

I'm having this same error in spring boot 3.3.2 but not with spring cloud but spring session redis backed by AWS serverless redis. I don't really understand it, and it seems like an invalidated session should be handled by default without throwing errors?

This seems related to #1277 possibly?
