tudo funciona perfeitamente ate eu incluir isso…
tabela tb_bolsa
<many-to-one name="tbInstituicao" class="TbInstituicao" fetch="select">
<column name="INS_ID" precision="10" scale="0" not-null="true" />
</many-to-one>
tabela tb_instituicao
<set name="tbBolsas" inverse="true">
<key>
<column name="INS_ID" precision="10" scale="0" not-null="true" />
</key>
<one-to-many class="TbBolsa" />
</set>
o erro…
