Code:

   <class
      name="Pessoa"
      table="Pessoa"
   >   


      <id
         column="idPessoa"
         name="idPessoa"
         type="java.lang.Integer"
      >
         <generator class="increment">
         </generator>
      </id>   
   <discriminator
      column="TipoPessoa"
      type="string"

   />   
      <property
         name="Nome"
         column="Nome"

         type="string"
         not-null="true"
        >
      </property>
   </class>
   <subclass
      name="PessoaJuridica"
        extends="Pessoa"
      discriminator-value="PessoaJuridica"
   >   

      <property
         name="CNPJ"
         type="java.lang.Integer"
         not-null="true"
        >
      </property>
</subclass>
   <subclass
      name="Partido"
        extends="PessoaJuridica"
      discriminator-value="Partido"
   >   

      <property
         name="Sigla"
         type="string"
         not-null="true"
        >
      </property>

Description:
I defined 3 classes, each one is a subclass discriminated by value:
C extends B extends A.
I defined C property 'x' as not null.
HBM2DDL is generating not null constraint for x, but it isn't right, becouse objects B and A will not have this property. And it worked fine on hibernate 2.
Am I right or should I change something in mapping ? :-)
