[Springframework-developer] Hibernate 3

[Colin S. <col...@ex...>]

Hibernate 3 is now out in Alpha. We should probably start thinking about 
how to add support for it, and a timeframe.

It's actually good that we didn't do anything before this, as there have 
been 4-5 bug fixes in Hibernate related session handling and transaction 
code the last few weeks. Since Hibernate 3 is in an entirely different 
package, what I think is probably the only viable option given that 
people are going to be using Hibernate2 for a long time yet, is to build 
up a parallel hierarchy of the support classes, probably with the same 
package names, but 'hibernate3' instead of just 'hibernate'. Arguably, 
the class names might make sense to have the version too, since it would 
reduce confusion a lot.

In terms of a timeframe, this could happen at any time in the sandbox, 
and probably in the main source tree after 1.1 final is out. The main 
issue is developer time, although I see the work as being pretty 
straightforward to do a direct translation. It's definitely worth it to 
then figure out what makes sense to add given the enhanced capabilities.

One interesting thing I read in the release notes; Hibernate now throws 
unchecked exceptions instead of checked exceptions...
