ClassCastException while reading from Infinispan Cache after redeployment on Wildfly 8.2

I have a simple Infinispan local-cache (also tried distributed cache) on Wildfly 8.2. Everything is working fine until I do redeployment of my .WAR. After redeployment of my .WAR I get the following error:

Caused by: java.lang.ClassCastException: my.package.MyClass cannot be cast to my.package.MyClass

I lookup the Cache in a CDI Bean like this:

@Resource(lookup = CacheConstants.JNDI_CACHE_CONTAINER)
private CacheContainer container;

private Cache<String, MyClass> myCache;

.....

@PostConstruct
public void start() {
    myCache = container.getCache(CacheConstants.MyCacheName);
}

I know that the error occured because off different class loaders. Infinispan tries to cast the entity stored with the previous classloader which cannot work. But how to avoid this?
