Issue when enabling eager initialization and using hibernate-reactive

[lengors]

Expected Behavior

The application should boot successfully (just like when it has eager initialization of singletons disabled).

Actual Behaviour

When the eager initialization of singletons is enabled, the following error can be seen:
