    > It was reported that OrlaceAdapter throws when running with Oracle 11 driver [1]. The problem is caused by Oracle "optimizations" built in to the Adapter. While I found a quick fix for "optimizations" to work with the new driver, I think the whole idea that Cayenne should hardcode some special Oracle parameters in the adapter is lame. Aside from the fact that our own testing didn't find any benefits of those "optimizations", Cayenne should not reconfigure the Statements in a one-size-fits-all manner.
    > Now what's *really* lame is Oracle inability to pass various parameters in the JDBC URL, so you have to call their API directly. We'll be leaving this as an exercise for the end-users from now on.
