[hibernate-dev] API/SPI in 5.0

As we transition to 5.0 we have to make a lot of decisions wrt API/SPI methods that are no longer relevant. I think it is better to look at these individually. == Configuration I went ahead and made a preliminary decision here as I discussed in HHH-7164. The thinking is that we had some leeway here because Configuration had been deprecated (and pretty widely known to be deprecated based on StackOverflow and other sources). Basically I made Configuration a simple delegate to the new Metadata building code. I removed all the methods that exposed access to the org.hibernate.mapping objects that Configuration used to manage. --- == Integrator This one is a little tougher. In retrospect I think I would have just gone for a number of discrete contributor contracts. For example, usually Integrator is used to add event listeners, so an EventListenerContributor would have worked. Then I would have used Integrator as a grouping of contributors. == PersisterFactory (and persister constructors) Forms taking Configuration and org.hibernate.mapping objects should, imo, get removed. But I can live with deprecation if someone wants to "pound the table" for that. But realize that the Configuration+org.hibernate.mapping forms would not be called ever.
