Emmanuel Bernard resolved HHH-5089.
-----------------------------------

    Resolution: Rejected

Check hibernate.check_nullability=false
That probably works.

>                 Key: HHH-5089
>                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5089
>             Project: Hibernate Core
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 3.3.1
>         Environment: Windows XP
> Eclipse 3.5.1
> Teneo 1.0.3

> This issue somehow relates to HHH-4057 but is of much broader scope and pointing out a different aspect.
> Currently Hibernate checks the not-null constraint integrity persisting any object already on the object level (which is a quite early point in time; for loading objects, this might cause analoguous problems).
> The not-null XML attribute, however, is part of the <column> tag and therefore is assumed to match the characteristics of a column and not a mapped object property!
> I am facing severe problems with the current behaviour, as the not-null check is performed even before 
> any nullSafePut() method is executed for a customized Hibernate type, or even before any the any PreInsertEventListener / PreUpdateEventListener has a chance to transform null-values for properties to non-null values for database columns.
> Effectively, the flexibility to handle different nullability characteristics between columns and their mapped properties is thus reduced to zero.
