projeto @Jadadoc para Android no Eclipse falha com NullPointerException

Estou tentando gerar comentários javadoc no Eclipse para o meu projeto Android, mas continuo recebendo uma NullPointerException. O problema ocorre apenas quando tento gerar javadocs para classes que importam oAndroid Compatibility Library (android.support), anexado como um jar externo. Também refiro o Android 2.2 e vários projetos de bibliotecas, mas eles não causam esse erro por conta própri

100 warnings

O principal problema é o erro na parte inferio - Os 100 avisos envolvem apenas links para a documentação principal da biblioteca Android, que é um problema separado quenã causa o erro sem referência ao android.support. De fato, nenhum dos avisos diz algo parecido com "o pacote android.support não existe". Isso me leva a acreditar que o javadoc está encontrando a biblioteca de compatibilidade, mas que algo que envolve o jar ou a maneira como eu o refiro está causando um erro quando se trata da geração final do javado

Todas as idéias sobre o que pode estar causando o erro são apreciada
