[hibernate-issues] [Hibernate-JIRA] Updated: (HV-266) NullPointerException when trying to validate an object with a class-level constraint annotation.

[Marcus Brito (JIRA)]

     [ http://opensource.atlassian.com/projects/hibernate/browse/HV-266?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Marcus Brito updated HV-266:
----------------------------

    Attachment: UsuarioChaveValidator.java
                UsuarioChave.java
                Usuario.java

Here's all (I think) relevant files. The annotated bean, a custom constraint and it's validator. 

I'm using Hibernate Validator 4.0.1.GA and Hibernate 3.5.0.Beta-1.
