Hi, Im having a problem with TomCat.

Whenever I Shut down or restart the contaner when there is an active session, it throws the following error:

INFO - Cannot serialize session attribute org.apache.cocoon.webapps.authentication.components.DefaultAuthenticationManager /UserStatus for session CE6F170E366C1E487D80C78B1DCC3B18
java.io.NotSerializableException: org.apache.cocoon.components.CocoonComponentManager
    at java.io.ObjectOutputStream.writeObject0(Unknown Source)
    at java.io.ObjectOutputStream.defaultWriteFields(Unknown Source)
    at java.io.ObjectOutputStream.writeSerialData(Unknown Source)
    at java.io.ObjectOutputStream.writeOrdinaryObject(Unknown Source)
    at java.io.ObjectOutputStream.writeObject0 (Unknown Source)
    at java.io.ObjectOutputStream.defaultWriteFields(Unknown Source)

Does anyone know how I can solve this problem?
