Problema de converão com BooleanConverter no VRaptor 3.1.2

Estou tendo problemas com conversão de Boolean na minha aplicação, e o meu conversor de Boolean padrão do vratpor está assim:

package br.com.caelum.vraptor.converter;

import br.com.caelum.vraptor.Convert;
import br.com.caelum.vraptor.Converter;
import br.com.caelum.vraptor.ioc.ApplicationScoped;
import java.util.ResourceBundle;
import java.util.Set;

@Convert(value = Boolean.class)
@ApplicationScoped
public class BooleanConverter implements Converter<Boolean> {

    private static final Set<String> IS_TRUE;
    private static final Set<String> IS_FALSE;

    public BooleanConverter() {
        //compiled code
        throw new RuntimeException("Compiled Code");
    }

    public Boolean convert(String value, Class<? extends Boolean> type, ResourceBundle bundle) {
        //compiled code
        throw new RuntimeException("Compiled Code");
    }

    private boolean matches(Set<String> words, String value) {
        //compiled code
        throw new RuntimeException("Compiled Code");
    }
}
