The error started occurring for us when we upgraded hibernate versions from 4.2.21.FINAL to 5.3.4.FINAL. The logs say:
{panel:title=Error Log}
thread="http-nio-8080-exec-297" level=ERROR logger=org.hibernate.internal.ExceptionMapperStandardImpl - HHH000346: Error during managed flush [org.hibernate.exception.ConstraintViolationException: could not execute statement]
{panel}
They seem to occur when constraint violations occur happen and don't seem to have a direct adverse impact on callers. It looks like a potential anti-pattern/bug that is causing Hibernate, to both [log|https://github.com/hibernate/hibernate-orm/blob/master/hibernate-core/src/main/java/org/hibernate/internal/ExceptionMapperStandardImpl.java#L34-L41] and [throw|https://github.com/hibernate/hibernate-orm/blob/523b29af0481b19b3b477eafbe04b854f7fc60da/hibernate-core/src/main/java/org/hibernate/internal/SessionImpl.java#L3286-L3288] the error. |
