I think the issue is that Hibernate requires JBDC 3 APIs which is why 
you can't build it with JDK6 and when you use JDK5, you see this. I 
dunno how to resolve this but I know that some modules in Hibernate 
compile against 1.4 and others against 1.5 but they might not have API 
incompabilities like 1.5 to 1.6.

Maybe Steve can help with this since he's having to somehow deal with 
this to support JDBC4?
