Subject Re: [MERGE] txn-refactor

Hey Darren,

Looking through the code it looks like this more an API change than an actual redesign of
the transaction code? I like the resulting code a lot better than the existing way of doing
it. As far as i can see you wrapped the existing TransactionLegacy way of doing it (txn.start
/ txn.commit) inside of the new Transaction functions execute and executeWithException. So
if i understand it correctly, nothing changed in how transactions are actually handled, except
that the code can now be easily changed to use spring TX.

Also you made that changes to a couple of classes to use the new api, but the majority of
the classes still need to be done. It might be nice to annotate the TransactionLegacy class
with @Deprecated so we can easily identify what needs to be done?

The new code is not covered by any new unit test yet? I couldn't check the cobertura result
yet as there are some build and test failures. Can you have a look at this build :
 You can kick off that job yourself from jenkins if you like to do the full test. Didn't do
the noredist build test yet as the normal build failed.

In short there are some things to fix before we can merge this.
