java.lang.IllegalStateException ao declarar aspecto com Spring

Estou tentando declarar o seguinte aspecto:

@Aspect
@Component
public class UpperCaseAdvice {
     @Before("@target(annotations.Model)")
     public void toUpperCase(JoinPoint joinPoint){
          //faz alguma coisa
     }
}

Estou utilizando o spring-boot com tomcat embarcado. Ao tentar subir a aplicação, recebo a seguinte exception:

java.lang.IllegalStateException: The resources may not be accessed if they are not currently started
    at org.apache.catalina.webresources.StandardRoot.validate(StandardRoot.java:245)
    at org.apache.catalina.webresources.StandardRoot.getResource(StandardRoot.java:212)

Aparentemente tentando criar o bean: Error creating bean with name 'viewControllerHandlerMapping'.

Se eu comento a anotação @Before, a aplicação sobe. Alguém ja enfrentou esse problema?

Edit: Debugando percebi que o problema está na criação do bean de configuração do Tiles. em Algum momento na criação do bean a classe ServletContextResource tenta montar uma url relativa ao caminho definido como local para as definições do tiles. No caso /tiles/tiles-config-global.xml .

Minha classe de configuração:

@Configuration
public class TilesConfigurations {

@Bean
public UrlBasedViewResolver urlBasedViewResolver(){
    UrlBasedViewResolver resolver = new UrlBasedViewResolver();
    resolver.setExposeContextBeansAsAttributes(true);
    resolver.setViewClass(TilesView.class);
    return resolver;
}

@Bean
public TilesConfigurer tilesConfigurer(){
    TilesConfigurer configurer = new TilesConfigurer();
    configurer.setDefinitions("/tiles/tiles-config-global.xml");
    return configurer;
}
}

O que não entendo é o porque esse problema não acontece quando comento a anotação @Before

Edit 2: Full stacktrace
