LoadersConfigurationBuilder does not clear existing stores on read()

Hello,

I am upgrading infinispan configuration and I have following problem:

In old configuration, we use:

Configuration config;
JdbmCacheStoreConfig storeConfig = new JdbmCacheStoreConfig();
storeConfig.setLocation(location);
storeConfig.setCacheLoaderClassName("org.infinispan.loaders.jdbm.JdbmCacheStore");
storeConfig.setFetchPersistentState(true);
storeConfig.setIgnoreModifications(false);
storeConfig.setPurgeOnStartup(false);
config = lc.addCacheLoader(storeConfig).build();

manager = new DefaultCacheManager(new GlobalConfiguration(), config);

Configuration c = manager.getDefaultConfiguration();
c.setEvictionMaxEntries(maxEntries);
c.setExpirationLifespan(lifespan);
manager.defineConfiguration(name, c);

And this works fine. Now I am updating to new configuration:

ConfigurationBuilder configuration = new ConfigurationBuilder();
configuration.invocationBatching().enable();
JdbmCacheStoreConfigurationBuilder builder = new JdbmCacheStoreConfigurationBuilder(configuration.loaders());
builder.location(location).fetchPersistentState(true);
configuration.loaders().addStore(builder);
manager = new DefaultCacheManager(new GlobalConfigurationBuilder().build(), configuration.build());

And I want to change some properties from previous default configuration for named cache:

ConfigurationBuilder builder = new ConfigurationBuilder();
builder.read(manager.getDefaultCacheConfiguration());
builder.eviction().maxEntries(maxEntries));
builder.expiration().lifespan(lifespan);
manager.defineConfiguration(name, builder.build());
Cache<String, Object> cache = manager.getCache(name);
cache.start();

But I got following exception:

org.infinispan.CacheException: Unable to invoke method public void org.infinispan.loaders.CacheLoaderManagerImpl.start() on object of type CacheLoaderManagerImpl

I need some help how to solve this issue, when we were using the old deprecated configuration, this configuration scenarion works.

Thanks
