Esta manhã (horário da África do Sul), o Maven baixou o último jar do primefaces (versão 5.3). Enquanto meu projeto é configurado de maneira a implantar o projeto no meu Web Container (neste caso, Wildfly 9.0.1.Final), ele falhou na implantação devido à seguinte exceção:

Voltei ao PrimeFaces 5.2, por enquanto, para colocar o aplicativo em funcionamento.

Como resolvo esse problema?
