Hello,

I'm using cocoon 2.1.9 and am seeing some unusual behaviour when tomcat
shuts down.

I see a NotSerializableException thrown regarding CocoonComponentManager
and SessionContext[1]. To my knowledge, the application doest not store
any session contect in the session.

The cocoon application only uses pipelines and a few actions and
generators. We're not using Flowscript or Javaflow so was not expecting
to see this issue.

Does anyone know what likely to be causing this ?

Best,
Alec Bickerton
