Hey guys,
I've finished the port of all the Hibernate h2lc from the ehcache
source base into the hibernate-ehcache module.
Now, polishing this, I also addressed this mapping from old to new names.
You can see the simple fix here:
But I have a couple of questions here:
- Shouldn't the fact that some mapping happens be logged? Are there
going to stick around? Shouldn't the user be made aware of the fact
that he should change his config?
- Second level cache isn't (yet?) using "ServiceInitiator approach",
is this going to change ?
- Right now the mapping plan is "weak" in terms of typing since core
doesn't know anything about hibernate-ehcache. I guess, if second
level caching also goes the ServiceInitiator path, that will change,
right ?
I'll do the pull request as soon as I'm sure it's all ready for it.
Probably sometime tomorrow.
Thanks,
Alex

It would not necessarily require users to change config values. Just
update
the code that instantiates the RegionFactories
(org.hibernate.cache.internal.RegionFactoryInitiator) to understand the
legacy class FQN as well. Have a look at
org.hibernate.engine.transaction.internal.TransactionFactoryInitiator for an
example of somewhere else we do that.
