Expected behavior

I would expect a 302 redirect, when I have an invalid session id.

Actual behavior

I get a 500 error due to a null pointer exception.

Steps to reproduce

Login into your app and invalidate the session, by dropping the collection. After a refresh of the app you would get a 500 error.

Reactor Netty version

reactor-core-3.2.12.RELEASE

JVM version (e.g. java -version)

openjdk 11.0.5 2019-10-15 LTS
OpenJDK Runtime Environment Zulu11.35+15-CA (build 11.0.5+10-LTS)
OpenJDK 64-Bit Server VM Zulu11.35+15-CA (build 11.0.5+10-LTS, mixed mode)

OS version (e.g. uname -a)

Linux lenovo 5.3.0-23-generic #25-Ubuntu SMP Tue Nov 12 09:22:33 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
