Lucas, isso acontece com requisições normais via URL. No caso eu tenho uma URI no endereço /admin/degree/, e se eu digitar /admin/degree/xx retorna NullPointerException.
Paulo, atualizei para o 3.1.1. Tenho alguns componentes customizáveis que nada mais é que o próprio RequestExecution, onde apenas troco a chamada do ExecuteMethodInterceptor para o CustomExecuteMethodInterceptor. O log do erro está abaixo. Não coloquei todo o debug porque não tinha informações muito úteis, mas se precisar posso enviar.
O que eu noto é que quando um resource não é encontrado o method vem NULL em todos os interceptors, então no caso do InstantiateInterceptor na linha 40 há um method.getResource, porém method é NULL.
Ambiente é vraptor 3.1.1, glassfishv3, projeto web + módulo EJB remoto.
