Solutions

1. Check the custom collection persister class for a compatible constructor and public visibility.
2. Inspect the causal exception for the real instantiation error.

When it happens

Trigger: Hibernate bootstrap fails to create a configured custom implementation class.

Common situations: A custom persister/factory/resolver class is missing, non-public, or lacks the required constructor.
