> DataDomainActionBuilder.batchAction calls delegate.batchAction():
>     public SQLAction batchAction(BatchQuery query) {
>         return new DataDomainBatchAction(domain, (BatchAction) delegate.batchAction(query));
>     }
> That delegate, OracleActionBuilder in our case, has some special handling:
>     if (OracleAdapter.isSupportsOracleLOB() && OracleAdapter.updatesLOBColumns(query)) {
>             return new OracleLOBBatchAction(query, getAdapter());
> That class does not extend BatchAction (unlike the normal OracleBatchAction case) and the BatchAction cast fails.
> The DataDomainActionBuilder is new code in 3.0.  Either it shouldn't cast to BatchAction, or OracleLOBBatchAction should extend BatchAction.
> I've left this as a Major priority because it doesn't appear to be Oracle8-specific.
