                 Key: ISPN-5803
                 URL: https://issues.jboss.org/browse/ISPN-5803

          Components: JCache

If a a JCache is created using a read-through {{javax.cache.integration.CacheLoader}} using a custom Serializable key (in this case {{acme.MyCache$MyKey}}) a {{ClassCastException}} is thrown when trying to pass the key value of {{org.infinispan.marshall.core.MarshalledValue}} instead of {{MarshalledValue#get()}} into the {{CacheLoader}} instance.

{code}
java.lang.ClassCastException: org.infinispan.marshall.core.MarshalledValue cannot be cast to acme.MyCache$MyKey
	at acme.MyCache$2.load(MyCache.java:1) [my-app-1.0.0-SNAPSHOT.jar:]
	at org.infinispan.jcache.embedded.JCacheLoaderAdapter.loadKey(JCacheLoaderAdapter.java:65) [infinispan-jcache-8.0.1.Final.jar:8.0.1.Final]
{code}
