Yes, your fix looks more straightforward |

I didn't take into account that ultimateTargetClass only defers from proxy-classes but does not retain abstract super type information. |

Problem
Since Hibernate ORM
7.2.x,ManagedBeanRegistryImplenforces that the class returned byContainedBean::getBeanClassmust be identical to the requested bean type.Spring’s
SpringContainedBeancurrently returnsbean.getClass(), which for AOP-proxied beans is a synthetic CGLIB subclass rather than the user-defined type. This mismatch causes Hibernate to throw:Root cause
SpringContainedBeanmisinterprets the contract ofContainedBean::getBeanClass(): it must return the original target class, not the runtime proxy class.Solution
Use
AopUtils.getTargetClass(bean)instead ofbean.getClass()to defer the actual user-defined type of CGLIB/Java-proxy wrapper.
