Boa noite Djair Gomes da Silva.

Meu emissor tinha o mesmo problema, ocorreu depois que atualizei o Java(v7.25)

Resolvi o problema assim:

1º Em uma maquina com o Java desatualizado, entrei no diretório "C:Program Files" e copiei a pasta "Java".

2º Lancei a pasta na rede, recortei, fui no mesmo diretório só que desta vez na maquina que deu problema colei e substitui. E voilà tudo ok novamente.

*obs. Eu até postaria a pasta junto, porem é muito pesada.

Espero ter ajudado.

ok
obrigado,
já consegui.

estou com o mesmo erro inesperado, e chato isso... me ajudem
