[some one]

Hello,

Does any one have any idea why does this exception gets thrown.

 java.io.NotSerializableException: org.springframework.security.userdetails.hierarchicalroles.RoleHierarchyImpl

This happens in v 2.0.3

When is it happening? When you shut your server down?

The error shows up on server up. But I think you are right the fault happens on server shut down

Tomcat tries to serialize session data to disk on shutdown. On startup, it tries to rehydrate your sessions and can't handle RoleHierarchyImpl since it's not serializable. It looks like that's what's going on. :-)
