tapestry-service-cache with tapestry 5.3.*

[jqzone]

I want to use tapestry-service-cache (
https://github.com/ciaranw/tapestry-service-cache ) ,but it has a bug
with tapestry 5.3.*

In tapestry 5.3.* ,ServiceResources. getImplementationClass(), just return
null;

but in class
com.ciaranwood.tapestry.cache.services.advice.CacheMethodDecoratorImpl ,is
there a replacement of this or another way to use?

souce code
in com.ciaranwood.tapestry.cache.services.advice.CacheMethodDecoratorImpl

public <T> T build(Class<T> serviceInterface, T delegate, ServiceResources
resources) {

        String serviceId = resources.getServiceId();
        Logger log = resources.getLogger();
        Class<T> implementation = resources.getImplementationClass();

        if(implementation == null) {
            return delegate;
        }
