DefaultCacheManager is unnecessarily creating instances of LegacyConfigurationAdaptor to call static methods.
e.g.

@Override
public org.infinispan.configuration.cache.Configuration defineConfiguration(String cacheName, org.infinispan.configuration.cache.Configuration configuration)

{ defineConfiguration(cacheName, new LegacyConfigurationAdaptor().adapt(configuration)); return configuration; }

even though adapt() is a static method.
