Re: [eclipselink-users] QueryBasedValueHolder cannot be cast to UnitOfWo

[James Sutherland <jamesssss@xxxxxxxxx>]

Most of the stack is your app or spring, the EclipseLink part is only at the
end, but seems to be missing the caused by, is there more to the stack?

Also please describe exactly what you are doing to get this error, ideally
your code for your commit.

Caused by: javax.persistence.RollbackException:
java.lang.ClassCastException:
org.eclipse.persistence.internal.indirection.QueryBasedValueHolder
cannot be cast to
org.eclipse.persistence.internal.indirection.UnitOfWorkValueHolder
        at
org.eclipse.persistence.internal.jpa.transaction.EntityTransactionImpl.commitInternal(EntityTransactionImpl.java:102)
        at
org.eclipse.persistence.internal.jpa.transaction.EntityTransactionImpl.commit(EntityTransactionImpl.java:63)
        at
org.springframework.orm.jpa.JpaTransactionManager.doCommit(JpaTransactionManager.java:456)
        ... 105 more
