    When the component restart, it tries to recover itself by replaying notification operations from its persisted data, it seems that messages are sent to the wrong services.
    In the current case, it is sending subscribe messages to the se-kpi which do not know how to handle this type of messages :

I think you should do like 'standard' SU autogeneration endpoint.
The fisrt time an SU autogenerate endpoint is registered, the endpoint is calculated then persisted in the JBI descriptor and the related WSDL, then activated in the bus.
You should do the same with the notification's endpoint.

IN fact, it is not only when the se-notification restart but when all components are restarting, ie notification subscribers are not the same due to autogenerate, so the se-notification try to resend subscribes to unknown endpoints

It 's a regression. Previously, the generated endpoint was stored into the wsdl into the repository. i.e. the string 'petals:autogenerated' was replaced by 'petals:uid:xxxx'. So when the bus restarted, the wsdl used the same endpoint name as previously, and the value into the se-notif was great.
You must check the part when we change the wsdl at the endpoint name generation time.

Previous comment is false. Since the endpoint is an autogenerated one, on restart the endpoint name is not the same than the one which has been stored by the se-notification. In the se-notification code, the service endpoint returned is null and not checked, the interface is set on the message exchange and so the message router takes the first endpoint with the given interface : There are potentially tens of endpoint with this interface...

It seems that Petals ESB does not returns the right service on call org.ow2.petals.jbi.component.context.ComponentContextImpl.getEndpoint(QName, String) when endpoint is not found ie a ServiceEndpoint is returned even if there is no endpoint with the given value
