[hibernate-issues] [Hibernate-JIRA] Created: (HBX-865) ClassValidator cannot be instantiated while trying to open a new Session

[Christian Laakmann (JIRA)]

ClassValidator cannot be instantiated while trying to open a new Session
------------------------------------------------------------------------

         Key: HBX-865
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-865
     Project: Hibernate Tools
        Type: Bug

    Versions: 3.2beta9    
 Environment: Hibernate 3.2, Hibernate Tools 3.2beta9 and most recent Nightly
DB: MSSQL Server 2000 & HSQLDB
    Reporter: Christian Laakmann
 Attachments: Test.java, hibernate.cfg.xml

When I use the @NotEmpty Validator on a String property, Hibernate Tools is unable to open a new Session because the ClassValidator could not be instantiated.

Workaround was to replace @NotEmpty with @NotNull.
