Carlos, tudo bem ?

um chute é que o tomcat 7 não dá suporte para java 9, fora que o java 9 muda toda a parte de configuração e tudo mais.

Recomendo usar o java 8.

Bom dia,

Desinstalei o Java 9 e instalei o Java 8 e rodou sem nenhum WARNING ou ERRO.

Pelo que vi teve muitas mudanças com o Java 9. Queria usar ele pois é o mais atualizado, mas estou tendo muita dificuldade.

Vou usar o Java 8 mesmo por enquanto :)

Muito obrigado!
