Hhhmm, I know I did this change, but this is a point to be documented
:-) User will get the same experience and we need to clearly document
these incompatibilities, may be the migration tool should print a
WARNING if there is a custom mediator.
Thanks,
Ruwan

This is due to an API change. Now if your Serializer is extending
from AbstractMediatorSerializer, you have to override the
protected abstract OMElement serializeSpecificMediator(Mediator m);
Previously user had to override the
public OMElement serializeMediator(OMElement parent, Mediator m).
But this method is final now.
Thanks,

Hi,
When trying to deploy custom mediators in the latest packs
(wso2esb-4.0.0-SNAPSHOT) I came across the following exception.
Tried by uploading the mediator through the Management Console UI
('Home > Manage > ESB Artifacts > Add') and also by dropping the
.xar file to /repository/deployment/server/mediators/.
The particular mediator worked fine for the 3.0.1 packs. Does this
mean we cannot use the old .xar files in the latest releases?
