Ao fazer o deploy da minha aplicação eu faço uma interceptação com o ServletContextListener e utilizo um esquema de
new SchemaUpdate(cfg).execute(Boolean.TRUE, isUpdate);
o codigo acima atualiza as minhas entidades em base de dados, ou seja se eu criar um novo atributo em alguma de minhas entidades o hibernate faz essa verificação antes de subir a aplicação, porem esta gerenado o seguinte erro:
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown table 'system_sequences' in information_schema
