“Entiry classes from database wizard” and Postgresql domains

[vhubuo]

I am trying to create entity classes form database with Netbeans wizard "Entiry classes from database". But if the field type in database table is an a custom domain the type of field is set to "Serializable", but it should be String or Integer.
Because domains are just wrappers around "normal" Postgresql datatypes.
And if my table contains custom domain named "DESCRIPTION" then NetBeans crashes with null pointer exception.
How can I fix this?
