Thanks for helping me out with this.

I have one comment (for the log, perhaps others want to try that as well).

There is no setChannel method on the DataChannel Interface. I guess this
is a typo and should read like this?:

DataChannelCallbackInterceptor postInterceptor = new

Most of the callbacks are working now. But I can't seem to get the
prePersist method work as expected? PrePersist is never called, although I
registered all the possible events. Do you have an idea?

Thanks again,
