My next question is where/how to do this work. I'm my workspace copy of trunk, I've got JBC 2.0 compatible stuff written in the existing org.jboss.ebj3.cache.tree and org.jboss.ejb3.entity packages. I'm going to need to get that checked in at some point this week or early next week. But once I do that, the old 1.4.x compatible stuff is gone until we get the EJB3 project set up for different adapters. Is there a problem with converting EJB3 trunk to 2.0 compatibility, and then adding the 1.4.x adapters later? Or do you guys need 1.4 compatibility in trunk for some other purpose?
