The controller throws an ConstraintViolationException since the JPA Entity has a Pattern matching check for field role, which is enforced via Hibernate. But the Controller Advice receives the above exception as TransactionSystemException instead. Its not clear why the original exception is getting masked in the first place.
@Entity
public class Bar {
@Pattern(regexp = "^role-.*", message = "Role should conform to naming conventions")
private String role;
}
The exception being thrown
