-------------------------

I must restart and often it's Ok.

I think it's a problem of Serializable object, this problem begin with 3.1.0.Final,  BridgeRequestScopeManagerImpl is Serializable now.

Is there a Tomcat parameter to set ?

Do you've any idea ?

From looking at the Tomcat source, it looks like it's trying to load a previously active Session that was persisted before the server was last shutdown, but is failing to load the class.

Was a previous version of PortletBridge used before the server was shutdown with an active session?  I'm not sure where Tomcat would be storing the saved sessions, but if you were able to clear those it might resolve it.

Yes it's something like this.

Was a previous version of PortletBridge used before the server was shutdown with an active session?

-> No, it's the same version of PortletBridge before the server was shutdown.

I am going to look where Tomcat store the saved session (maybe temp but this folder is delete).

To finalize answer, there is a parameter to disable session persistence across Tomcat restarts in context.xml :

<Context>

<Manager pathname=""/>

</Context>
