> In some specific cases, if we want to define a configuration in which we disabled the L1 cache and the property onRehash, we can still face the following exception:
> {code}
> org.infinispan.config.ConfigurationException: Can only move entries to L1 on rehash when L1 is enabled
> 	at org.infinispan.config.ConfigurationValidatingVisitor.visitL1Type(ConfigurationValidatingVisitor.java:99)
> 	at org.infinispan.config.DelegatingConfigurationVisitor.visitL1Type(DelegatingConfigurationVisitor.java:183)
> 	at org.infinispan.config.Configuration$L1Type.accept(Configuration.java:3698)
> 	at org.infinispan.config.Configuration$ClusteringType.accept(Configuration.java:2462)
> 	at org.infinispan.config.Configuration.accept(Configuration.java:1459)

> 	at org.infinispan.manager.DefaultCacheManager.createCache(DefaultCacheManager.java:618)
> 	at org.infinispan.manager.DefaultCacheManager.getCache(DefaultCacheManager.java:514)
> {code}
> See below a TestCase that represents one way to face this issue:
> {code}
>    public void testConfig()
>    {
>       GlobalConfigurationBuilder gcb = GlobalConfigurationBuilder.defaultClusteredBuilder();
>       ConfigurationBuilder cb = new ConfigurationBuilder();
>       DefaultCacheManager manager = new DefaultCacheManager(gcb.build(), cb.build());
>       cb = new ConfigurationBuilder();
>       cb.clustering().cacheMode(CacheMode.DIST_SYNC).l1().disable().disableOnRehash();
>       manager.defineConfiguration("testConfigCache", cb.build());
>       manager.getCache("testConfigCache");
>    }
> {code}
