      1). Configure cache in invalidation mode in XML:

      <?xml version="1.0" encoding="UTF-8"?>
<infinispan xmlns="urn:infinispan:config:8.2">
    <cache-container default-cache="default">
        <transport cluster="jcache-cluster"/>
        <invalidation-cache-configuration name="user" mode="SYNC" statistics="true"/>
    </cache-container>
</infinispan>

      2). Provide cache loader configuration through JCache API:

      new MutableConfiguration<String, User>()
    .setReadThrough(true).setStoreByValue(true)
    .setCacheLoaderFactory(FactoryBuilder.factoryOf(UserCacheLoader.class));

      Cache loader can be trivial:

      public class UserCacheLoader implements CacheLoader<String, User> {
    @Override
    public User load(String username) {
        return new User(username);
    }
}

      3). Load serveral users into the cache.
      4). Call `javax.cache.Cache.removeAll()` method on the cache instance.

      1). Configure cache in invalidation mode in XML: <?xml version= "1.0" encoding= "UTF-8" ?> <infinispan xmlns= "urn:infinispan:config:8.2" > <cache-container default-cache= "default" > <transport cluster= "jcache-cluster" /> <invalidation-cache-configuration name= "user" mode= "SYNC" statistics= "true" /> </cache-container> </infinispan> 2). Provide cache loader configuration through JCache API: new MutableConfiguration< String , User>() .setReadThrough( true ).setStoreByValue( true ) .setCacheLoaderFactory(FactoryBuilder.factoryOf(UserCacheLoader.class)); Cache loader can be trivial: public class UserCacheLoader implements CacheLoader< String , User> { @Override public User load( String username) { return new User(username); } } 3). Load serveral users into the cache. 4). Call `javax.cache.Cache.removeAll()` method on the cache instance.

      When cache is configured through JCache API as a read-through cache with some cache loader Infinispan puts cache values provided by that loader in place of keys. It causes `java.lang.ClassCastException` after calling of `javax.cache.Cache.removeAll` method. Iteration on cache also turns out to be broken.
