Emmanuel,
Great stuff indeed. Couple of things:
- Just updated the git repo and I get some compilation failures such as:
getPropertyColumnInsertable() misssing in OgmEntityPersister
Have you compiled and installed the core module. I have made minor changes to it.
mvn clean install -pl parent,core,testing,ogm
should do the trick.
- In InfinispanDialect, could LockMode.PESSIMISTIC_READ would be mapped to a no lock
strategy? Thanks to MVCC, Infinispan does not lock read ops.
I am not sure and when I discussed that on IRC people did not give me conclusive arguments
so I've used the safe approach for now.
The semantic required is described in the JPA 2 spec section 3.4.4.2. One key element is
pessimistic ie we fail fast or we guarantee it if the lock is acquired.
