Yes Vlad, I can confirm that this error appears also in Hibernate 5.2.4 which is my current version.

Also i have Oracle 11gR2 as DB and my SQL dialect is org.hibernate.dialect.Oracle10gDialect.

I didn't try to implement any workaround because i preferred to switch to another custom implementation of Bulk Id Strategy that uses only one table. i'm talking about Single Global Temporary Table Bulk Id Strategy for Hibernate .
