Jasper - gera relatório com 1 página a mais (em "branco")

Pessoal estou com problema usando o Jasper Report. Eu tenho um relatório (na verdade vários) que praticamete não possue conteudo: ele possui o cabeçalho, o rodapé e possui um <detail> que possui apenas um sub relatório. O problema é que quando o relatório é gerado no final do relatório ele sempre gera uma página a mais só que sem conteudo.
Alguem pode me ajudar????

&lt;detail&gt;
