[DISCUSS] Propose additional uses for openjpa-integration

[Donald Woods]

There are two scenarios that I'd like us to consider using the 
openjpa-integration component for testing in trunk -

1) Validation - using a new integration subproject to test our optional 
bean validation support against one or more providers.  This will allow 
us to keep the junits in openjpa-persistence-jdbc focused on the default 
no validator scenarios.

2) Lock/Timeout testing - moving most of the lockmgr and lock/query 
timeout tests out of openjpa-persistence-jdbc to a new integration 
subproject to reduce the time required to run the main-line tests

Both of the above subprojects would be setup to always run in the tests 
goal, so top-level builds would still run all of the existing plus new 
junits.


A future scenario to consider, would be moving DB specific tests (that 
target a single DB like Oracle, DB2, ...) into integration subprojects, 
so every junit that remains in openjpa-persistence-jdbc is always active 
(not excluded in surefire or skipped due to the DBDictionary) and should 
always pass on every supported DB.
