Last week, both Andrea and I saw BulkManipulationTest run successfully using Oracle JDBC 12.1.0.1.0 with Oracle12cDialect.

When I run BulkManipulationTest, it fails with:

Using 12.1.0.2.0, BulkManipulationTest fails with the same stacktrace as in HHH-9983.

I've also confirmed that the fix for HHH-9983 fixes this issue, so I'll mark this as a duplicate.
