Reproducible: Always

Steps to Reproduce:
1. Define a sequence generator and a table generator with different names at the mapping file level in the mapping XML
2. Try to run the application

Note: The same exception is thrown with the following cases:
- table generator at the mapping file level in the mapping XML + sequence generator at the mapping level in the Java entity
- table generator at the entity level in the mapping XML + sequence generator at the entity level in the Java entity
